Acetic acid methyl ester is the ester of acetic acid and methanol. He is also known as methyl acetate or according to the new nomenclature Methylethanoat.

Properties

Methyl acetate is a colorless liquid with a high vapor pressure and low flash point (-13 ° C). Therefore, pay attention to the handling and use of methyl acetate mainly due to good ventilation and the avoidance of sources of ignition. Methyl acetate is readily soluble in water with 319 g / l at 20 ° C.

Production

It is produced by acid-catalyzed esterification of acetic acid with methanol:

The removal of the water formed the above equilibrium is shifted to the products page (see also law of mass action ).

Use

Acetic acid methyl ester is used as a solvent in for example paints, coatings and adhesives.
