Acetic acid vinyl ester. Chemical formula: C4H6O2.
It is a clear, colorless liquid with a characteristic ethereal odor. The boiling point is 73 ° C. Vinyl acetate is highly soluble in organic solvents and to a limited extent in water. It is obtained by vinylation of acetic acid with acetylene in the presence of catalysts.
In terms of chemical properties, vinyl acetate is a typical vinyl ether. In solutions of acids or alkalis, it hydrolyzes to form acetic acid and acetaldehyde. Reacts with carboxylic acids in the presence of Hg salts to form new vinyl esters. It polymerizes under the influence of light, radical initiators.
The modern method of producing vinyl acetate is, in fact, a special kind of the Wacker process, where acetic acid is used instead of water.
Vinyl acetate has a narcotic and general toxic effect, irritates the eyes and upper respiratory tract. The permissible level of vinyl acetate emitted into the air from building materials is 0.2 mg / m3.
Synonyms and international names:
VAM (Vinyl acetate monomer)
Application:
-Vinyl acetate is the main raw material for the production of polyvinyl acetate, polyvinyl alcohol and acetals based on it, as well as various copolymers of great industrial importance.
-Vinyl acetate is used as a monomer to obtain polymers and copolymers that have a very wide range of practical applications: from vinyl records (in the form of a copolymer with vinyl chloride) to various kinds of adhesives, varnishes and emulsion paints based on copolymers of vinyl acetate with acrylic acid esters.
