Etheyl Vinyl Acetate

The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst.

Etheyl vinyl acetate.

Vinyl acetate c4h6o2 cid 7904 structure chemical names physical and chemical properties classification patents literature biological activities safety. Coffee beans and tea leaves are decaffeinated with this solvent. Eva shows good barrier and stretch properties. Vinyl acetate is the acetate ester of vinyl alcohol.

For example it is commonly used to clean circuit boards and in some nail varnish removers acetone is also used. Poly 1 vinylpyrrolidone co vinyl acetate 1 product result. It shows good chemical resistance. The weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene.

Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate. Ethylene vinyl acetate is a flexible and transparent thermoplastic. United states pharmacopeia usp reference standard. Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va.

Product name cas number. The va comonomer interferes with chain packing reducing crystallinity and thus lowering tm and improving transparency when compared with ldpe. As the va content increases crystallinity decreases until at 50 the eva is totally amorphous. Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial.

2 1 2 methoxymethoxy ethyl vinyl 4 methyl 6 oxobicyclo 2 2 2 oct 2 yl acetate 1 product result match criteria. 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. 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.
