What Is Vinyl Acetate

Vinyl acetate ch 2 cho 2 cch 3 is prepared from ethylene by reaction with oxygen and acetic acid over a palladium catalyst under the action of free radical initiators vinyl acetate monomers single unit molecules can be linked into long branched polymers large multiple unit molecules in which the structure of the vinyl acetate repeating units is.

What is vinyl acetate. A colorless liquid with a strong sweet odor vinyl acetate is also often referred to as vam or acetic acid vinyl ester. Raw material for many polyvinyl resins. Since it is highly flammable and volatile with a. Vinyl acetate is used to make other industrial chemicals.

Vinyl acetate is an industrial chemical that is produced in large amounts in the united states. The unique chemical properties of vinyl acetate derivatives make them perfectly equipped to tackle a range of industrial applications. 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. Vinyl acetate is the acetate ester of vinyl alcohol.

It is very flammable and may be ignited by heat sparks or flames. Vinyl acetate monomer vam is a key intermediate used in the making of a number of polymers and resins for adhesives coatings paints films textiles and other end products. It is a monomer by nature that is reactive with a wide variety of chemicals and vinyl acetate is produced by catalyzing acetic acid with ethylene and oxygen in a reactor. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst.

The largest derivative is polyvinyl acetate pva which is mainly used in adhesives as it has good adhesion properties to a number of substrates including paper wood. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate the weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene. Vinyl acetate monomer also known as acetic acid ethenyl ester acetic acid ethylene ether acetoxyethene 1 acetoxyethylene ethenyl ethanoate ethenyl acetate and acetic acid vinyl ester is a colourless mobile liquid with a pungent odour.

1 acetoxyethylene ethenyl acetate ethenyl ethanoate vac vinyl acetate monomer vinyl ethanoate colorless liquid with a pleasant fruity odor. While vinyl acetate is rarely used in its pure form its derivatives are used throughout various industries. Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial.
