vinyl acetate

[′vīn·əl ′as·ə‚tāt]
(organic chemistry)
CH3COOCH:CH2 A colorless, water-insoluble, flammable liquid that boils at 73°C; used as a chemical intermediate and in the production of polymers and copolymers (for example, the polyvinyl resins).

Vinyl Acetate

 

a vinyl ester of acetic acid (CH2=CHOCOCH3), a colorless liquid with a weak lachrymatory effect. Boiling point, 73° C; melting point, -84° C; density at 20° C, 0.934 g/cm3. It has limited solubility in water (2.5 percent) but is readily soluble in organic solvents. It polymerizes and copolymerizes readily with other vinyl compounds. Vinyl acetate is made by vinylation of acetic acid with acetylene in the presence of catalysts:

CH≡CH+HOCOCH3→CH2=CH—OCOCh3

Polymers and copolymers of vinyl acetate are widely used for making glues and lacquers, for impregnation, and for making floor tiles and phonograph records. Polyvinyl acetate, a product of the polymerization of vinyl acetate, is used as a raw material for making polyvinyl alcohol.
