Vinyl acetate is the acetate ester of vinyl alcohol.

Etheyl vinyl acetate.

The food and drug administration fda has stated that ethylene vinyl acetate is safe when used in food production packaging or transportation and it s not an especially dangerous material. Product name cas number. Ethylene vinyl acetate is a flexible and transparent thermoplastic. Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va.

Ethylene vinyl acetate offers good low temperature flexibility. Coffee beans and tea leaves are decaffeinated with this solvent. The weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst.

United states pharmacopeia usp reference standard. It shows good chemical resistance.

As the va content increases crystallinity decreases until at 50 the eva is totally amorphous. Since vinyl alcohol is highly unstable with respect to acetaldehyde the preparation of vinyl acetate is more complex than the synthesis of other acetate esters.

Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate. Poly 1 vinylpyrrolidone co vinyl acetate 1 product result. For example it is commonly used to clean circuit boards and in some nail varnish removers acetone is also used.
