Methyl Acetate For Coating

METHYL ACETATE

Product Description:

CAS NO: 79-20-9

Methyl Acetate(MA) appears as a clear colorless liquid with a fragrant odor. Moderately toxic. Flash point 14°F. Vapors heavier than air. Methyl acetate is an acetate ester resulting from the formal condensation of acetic acid with methanol. A low-boiling (57 ℃) colourless, flammable liquid, it is used as a solvent for many resins and oils. It has a role as a polar aprotic solvent, a fragrance and an EC 3.4.19.3 (pyroglutamyl-peptidase I) inhibitor. It is an acetate ester, a methyl ester and a volatile organic compound.

Methyl Acetate, also known as MeOAc, acetic acid methyl ester or methyl ethanoate, is a carboxylate ester with the formula CH3COOCH3. It is a flammable liquid with a characteristically pleasant smell reminiscent of some glues and nail polish removers. Methyl acetate is occasionally used as a solvent, being weakly polar and lipophilic, but its close relative ethyl acetate is a more common solvent being less toxic and less soluble in water. Methyl acetate has a solubility of 25% in water at room temperature. At elevated temperature its solubility in water is much higher. Methyl acetate is not stable in the presence of strong aqueous bases or aqueous acids. Methyl acetate is not considered a VOC in the USA. Methyl acetate is produced industrially via the carbonylation of methanol as a byproduct of the production of acetic acid.Methylacetate also arises by esterification of acetic acid with methanol in the presence of strong acids such as sulfuric acid; thisproduction process is famous because of Eastman Kodak's intensified process using a reactive distillation.

FAQ:

Q1: What is the difference between methyl acetate and acetone?

A1: Unlike Acetone, methyl acetate has a low odour that is ideal for use in furniture and automotive applications. Methyl acetate can also be used in cosmetics such as perfumes and removers of nail polishes, resulting in less damage to nails than acetone.

Q2: How is methyl acetate produced?

A2: Methyl acetate can be produced by subjecting methanol and acetic acid to esterification in the presence of an esterification catalyst and subsequently separating the products in the presence of an entrainer with the help of two distillation columns.
