MEK is a liquid solvent used in surface coatings, adhesives, printing inks, chemical intermediates, magnetic tapes and lube oil dewaxing agents. 

MEK also is used as an extraction medium for fats, oils, waxes and resins.   

It is a highly efficient and versatile solvent for surface coatings.  

Because of its effectiveness as a solvent, MEK is especially valuable in formulating high solids coatings, which help to reduce emissions from coating operations.  

MEK is a natural component of many foods, including apple juice, beans, chicken, honey and a variety of cheeses. Synonyms for MEK are 2-butanone, ethyl methyl ketone, and methyl acetone.

Methyl ethyl ketone appears as colorless fairly volatile liquid with a pleasant pungent odor. Flash point 20°F. Vapors heavier than air. Does not react with water or many common materials. Stable in normal transportation. Irritates the nose, eyes, and throat. Combustion may produce toxic materials. Density lb / gal. Used as a solvent, for making other chemicals, and for production of wax from petroleum. 2-Butanone is a manufactured chemical but it is also present in the environment from natural sources. It is a colorless liquid with a sharp, sweet odor. It is also known as methyl ethyl ketone (MEK). 2-Butanone is produced in large quantities. Nearly half of its use is in paints and other coatings because it will quickly evaporate into the air and it dissolves many substances. It is also used in glues and as a cleaning agent. 2-Butanone occurs as a natural product. It is made by some trees and found in some fruits and vegetables in small amounts. It is also released to the air from car and truck exhausts.

Methyl Ethyl Ketone  Chemical Structure Composition.

Production

The main commercial production route for methyl ethyl ketone is through the dehydrogenation of secondary butanol although newer technology involves the direct oxidation of n-butene in solution, using palladium and cupric chlorides as catalysts.

The Chinese market is the main driver for the demand of MEK.

Uses

The majority demand is from the paints and coatings industry as a low viscosity solution can be obtained without it affecting the film properties of the product.  These lacquers are used in the automotive, electrical goods, and furniture industries.

MEK is also used in the manufacture of plastics and textiles, the manufacture of printing inks, and also in rubber-based industrial cements.  It is also used in the chemical industry as it is a precursor to methyl ethyl ketone peroxide which is itself used as a catalyst to initiate the polymerisation of polyester resins used in fibre-glass reinforced products.

ATAMAN CHEMICALS is one of the largest chemical distributor in Europe.

ATAMAN CHEMICALS is handling the storage, transport, export & import formalities of Methyl Ethyl Ketone globally.

MEK is an active & organic solvent. 

It is in a clear, inflammable and liquid form. 

It is in the ketone groups. 

It has a high evaporation rate. 

It is one of the most widely used ketones in the industry.

Areas of usage:

It is used in organic synthesis reactions.

It is used in the sectors of paint, coating and detergent.

Butanone, also known as methyl ethyl ketone (MEK),[a] is an organic compound with the formula CH3C(O)CH2CH3. 

This colourless liquid ketone has a sharp, sweet odor reminiscent of acetone. 

It is produced industrially on a large scale, but occurs in nature only in trace amounts.

It is partially soluble in water, and is commonly used as an industrial solvent.

It is an isomer of another solvent, tetrahydrofuran.

Methyl ethyl ketone appears as colorless fairly volatile liquid with a pleasant pungent odor.

Applications

As a solvent

Butanone is an effective and common solvent and is used in processes involving gums, resins, cellulose acetate and nitrocellulose coatings and in vinyl films.

For this reason it finds use in the manufacture of plastics, textiles, in the production of paraffin wax, and in household products such as lacquer, varnishes, paint remover, a denaturing agent for denatured alcohol, glues, and as a cleaning agent. 

It has similar solvent properties to acetone but boils at a higher temperature and has a significantly slower evaporation rate.

Unlike acetone, it forms an azeotrope with water,making it useful for azeotropic distillation of moisture in certain applications. 

Butanone is also used in dry erase markers as the solvent of the erasable dye.

As a plastic welding agent

As butanone dissolves polystyrene and many other plastics, it is sold as "model cement" for use in connecting parts of scale model kits. 

Though often considered an adhesive, it is actually functioning as a welding agent in this context.

Other uses

Butanone is the precursor to methyl ethyl ketone peroxide, which is a catalyst for some polymerization reactions such as crosslinking of unsaturated polyester resins. 

Dimethylglyoxime can be prepared from butanone first by reaction with ethyl nitrite to give diacetyl monoxime followed by conversion to the dioxime

Butanone; 2-Butanone; Ethyl methyl ketone; Ethylmethylketone; Methyl ethyl ketone; MEK; Methylpropanone; Methylacetone. CAS Number:  

Flammability

Butanone can react with most oxidizing materials, and can produce fires.

It is moderately explosive, requiring only a small flame or spark to cause a vigorous reaction.

Butanone fires should be extinguished with carbon dioxide, dry agents, or alcohol-resistant foam.

Concentrations in the air high enough to be flammable are intolerable to humans due to the irritating nature of the vapor.

Health effects

Butanone is a constituent of tobacco smoke.[16] It is an irritant, causing irritation to the eyes and nose of humans.

Serious health effects in animals have been seen only at very high levels. 

These included skeletal birth defects and low birth weight in mice, when they inhaled it at the highest dose tested ( ppm for 7 hours/day).

There are no long-term studies with animals breathing or drinking it, and no studies for carcinogenicity in animals breathing or drinking it: There is some evidence that butanone can potentiate the toxicity of other solvents, in contrast to the calculation of mixed solvent exposures by simple addition of exposures.

As of , some reviewers advised caution in using butanone because of reports of neuropsychological effects.

The polymerization reactions of the synthesized N-alkyl(methyl, n-butyl, n-heptyl, n-dodecyl)-N-allyl-N-(P-chloro)allylamines (AABA) were carried out in solutions of mineral acids (HCl, HNO3, H3PO4) in the presence of thermal initiators - ammonium persulfate (AP) and azo-bis-isobutyric acide dinitrile (ABD). Radical polymerization of AABA was performed using AP and ABD with initiator concentration mol/l and at a temperature C, the reaction was hours. In this way, it is not possible to obtain sufficiently high molecular mass of the polymerization products, although PA is more effective than ABD. However, during the photopolymerization of AABA in solutions of concentrated acids in the presence of photoinitiators - uranyldiaquadiacetate and uranyldipivalate with an initiator concentration of mol/l, water soluble polymers were obtained with sufficiently high characteristic viscosity for a given amine.

funduszeue.info Introduction

The polymers based on diallyl monomers occupy an important place among synthetic po-lyelectrolytes, which can be used as coagulants, flocculants, soil structuring agents, as well as for purification of drinking and waste water. Therefore, the synthesis of new diallyl monomers and polymers containing functional groups, as well as the corresponding polyelectrolytes with adjustable hydrophilic-hydrophobic balance is a very urgent task.

The study on the radical polymerization processes of diallyl monomers, in particular, on the basis of N-alkyl-N-allyl-N-(P-chloro)allyl-amines is of scientific and practical interest. It should also be noted that there are small date in the literature devoted to the study of the kinetic features of the polymerization of N-alkyl-N-allyl-N-(P-chloro)allylamines and their salts in protonated form, which would contain hydro-phobic N-alkyl substituents.

In the literature, there are no date on the synthesis and polymerization of N-alkyl-N-allyl-N-(P-chloro)allylammonium dihydrophosphates. But there is information about the polymerization N-alkyl-N,N-diallylammonium dihydrophosphates [1, 2].

Synthesis of investigated compounds was made on case N-allyl-N-(P-chloro)aHyl-N-methylamine (ABMA). A two-liter, four-necked flask equipped with a stirrer, reflux condenser, thermometer, dropping funnel, pour a portion of a 25% aqueous solution of methylamine g (1 mol) and g of allyl chloride drop by drop during 1 h and after 7 h g (mol) (P-chloro)allyl chloride for 1 h and then a 50% aqueous solution of sodium hydroxide (80 g, 2 mol). The feed rate of the reagents is adjusted so that the temperature in the reaction mass does not exceed C. To remove excess heat using a water bath with ice. After adding the sodium hydroxide solution, the reaction mass is slowly warmed to C. After cooling the reaction mixture, the upper layer is separated and kept over granulated NaOH for 40 h.

Results and discussion

In connection with widespread use of cationic polyelectrolytes in various branches of industry, it seems natural for researchers to synthesize new polyelectrolytes which would have a complex of valuable properties with adjustable hydrophilic-hydrophobic balance basis on the diallyl monomers. To this end, we have a number of N-alkyl-N-allyl-N-(P-chloro)allylamines synthesized to the scheme [5, 6]:

It is known that radical polymerization of tertiary amines in the form of free bases proceeds only with the formation of low molecular mass oligomers. This is due to the side effect of the monomer-radical cleavage of the hydrogen atom of the -CH2 group of the allyl substituent, as is well known, which easily occurs in the case of diallylamines in the basic form. In this case, the chain transfer reaction to the monomer leads to the formation of a weakly reactive allylic transfer radical, the loss of the active radical center and the attenuation of the polymerization process. This reaction is characterized as a degradation chain transfer to the monomer [7]. This is mainly due to the presence of isolated degraded chain transfer to the monomer, which complicates the methods of their deep research. Therefore, the search for approaches to the synthesis of of N-alkyl-N-allyl-N-(P-chloro)allylamines which reduce the

contribution of the degradation chain to the monomer, can open the way to obtaining polymers with desired practical properties and high molecular mass (MM).

The reactions of radical polymerization of the amines synthesized by us earlier were carried out in solutions of various mineral acids (HCl, HNO3, H3PO4) in the presence of a thermal initiators (T=C) and photochemical method (T=C).

The radical polymerization of ABMA was performed using UA and AID with an initiator concentration of mol/l at C, the reaction time was equal to h. The results are shown in Table 1. As can be seen from table 1, in this way it is not possible to obtain sufficiently high values of the MM of the polymerization products, although PA is more effective than ABID. The polymer yield in all cases did not exceed 10%.

However, during the polymerization of ABMA (C, X= nm) in solutions of concentrated acids in the presence of UA and UP with a concentration of Cin=4'10"4 mol/l, water-soluble polymers were obtained with sufficiently high characteristic viscosity for a given class of compounds. The results of photopolymerization are shown in Table 2, from which it is clear that highest MM polymer values were obtained in the case of ABMA in a solution of ortho-phosphoric acid (85% aqueous solution) in the presence of UA as an initiator, and the MM value does not depend on the amine/acid ratio. The MM values of the obtained polymerization products, as well as the yield of polymers, are higher in the case of polymerization of ABMA in mineral acids than in the case of polymerization in the presence of thermal initiators (C). It should be noted that in the absence of an initiating system, the reaction of polymerization of ABMA in acid is nit observed.

As can be seen from table 2, UA is fairly effective initiating system. It is known that salts of uranyl when absorbed by a quantum of tight are restored, chemically from U to U4+. When light is absorbed, the uranyl ion goes into an excited state to form the U5+ product.

U+ + hv (U+)*

(U+)* + "OOCR [U02+, R] + C02T

In this case, the radicals either die due to intracellular reactions, or dissociate with the release of the radical R', which initiates polymerization, into the bulk [8]. Chlorine anions have a strong inhibitory effection the rate of photochemical reduction of the uranyl ion U6+ to U4+, nitrate anions have a weak inhibitory effect, and ortho-phosphoric acid anions do not have a marked inhibitory effect [9]. Apparently, this fact contributes to the creation of an effective system in which ABMA is capable of polymerizing with the formation of a soluble polymer in water.

Analysis of 13C NMR spectrum of the polymer suggests that the polymerization proceeds through the double bonds of the formation of a diallyl groups via a cyclo linear mechanism with the formation of a polymer with a pyrrolidine structure [].

Conclusions

1. Radical polymerization of AABA was carried out in solutions of mineral acids (HCl, HNO3, H3PO4) using thermal initiators - PA and ABD (Cin= 4'mol/l, at C). It is shown that this method fails to obtain sufficiently high MM values of polymerization products. However, during the photopolymerization of AABA (T=C, ^= nm) in solutions of concentrated acids in the presence of photoinitiators - uranyldiaquadiacetate and ura-nyldipivalate with an initiator concentration of 4' mol/l, water-soluble polymers were obtained with sufficiently high characteristic viscosity for a given amine.

2. It was established that the polymerization of AABA proceeds through the double bonds of the diallyl groups via a cyclo linear mechanism with the formation of a polymer with a pyrrolidine structure.

Реакции полимеризации синтезированных нами ранее ^алкил(метил, н-бутил, н-гептил, н-додецил)-Ы-аллил-N-(ß-хлор)аллиламинов (ААБА) проводили в растворах минеральных кислот (HCl, HNO3, H3PO4) в присутствии термических инициаторов - персульфата аммония (ПА) и динитрила азо-бис-изомасляной кислоты (ДАК). Радикальную полимеризацию ААБА проводили с использованием ПА и ДАК с концентрацией инициатора моль/л, температура - С, продолжительность реакции - ч. Указанным способом не удается получить достаточно высокие значения молекулярных масс продуктов полимеризации, хотя ПА является более эффективным, чем ДАК. Однако при проведении фотополимеризации ААБА (Т=С, Х= нм) в растворах концентрированных кислот в присутствии фотоинициаторов - диаквадиацетата уранила и диаквадипивалата уранила с концентрацией моль/л были получены водорастворимые полимеры с достаточно высокими значениями характеристической вязкости для изученного амина.
