Read： 1423 Time：12months ago Source：Transform the World with Simplicity

Vinyl acetate is an important organic chemical raw material and has a wide range of uses. It is prepared by the addition reaction of acetic acid and ethylene under the action of a catalyst. The properties and uses of vinyl acetate are as follows:

1. properties

1. Physical properties
vinyl acetate is a colorless, transparent, flammable, and irritating liquid. It is insoluble in water but miscible with many organic solvents. The boiling point of vinyl acetate is low and easy to volatilize.

2. Chemical properties
vinyl acetate molecules contain carbon-carbon double bonds and ester groups, so it has strong chemical reactivity. It can occur addition, polymerization, ester exchange and other reactions.

2. Uses

1. Polymerization
Vinyl acetate can be used as a monomer to generate polyvinyl acetate through polymerization. Polyvinyl acetate has good oil resistance, chemical resistance and electrical insulation, can be used to make adhesives, coatings, plastics and so on.

2. Copolymerization
vinyl acetate can also be copolymerized with other monomers to produce polymers with various properties. For example, vinyl acetate and methyl acrylate copolymerization, can be more water-resistant, weather-resistant polymers for the production of architectural coatings, waterproof materials.

3. Transesterification
The ester group of vinyl acetate can be transesterified to generate new ester compounds. This property has important applications in organic synthesis.

In conclusion, vinyl acetate, as an important organic chemical raw material, has a wide range of uses in the field of chemical production raw materials. Through the in-depth understanding of the nature and use of vinyl acetate, we can better apply it in actual production and promote the development of the chemical industry.
