What Is Vinyl Acetate?

Vinyl acetate is another name for vinyl acetate. Other names include vinyl acetate and vinyl acetate, which are the raw materials for the preparation of vinylon. It is a colorless liquid with a sweet ether flavor; slightly soluble in water, soluble in alcohol, acetone, benzene and chloroform. Vinyl acetate is flammable and its vapor can form explosive mixtures with air. Case of open flame and high heat can cause combustion and explosion. It can react with oxidants. Extremely easy to polymerize by the action of heat, light or a small amount of peroxide. Commodities containing inhibitors can also polymerize violently when contacted with peroxide. Its vapor is heavier than air, and can spread to a relatively low place at a lower place. It will reignite when exposed to open flames. Mainly used in the production of polyvinyl alcohol resins and synthetic fibers. Its monomers can be copolymerized to produce a variety of adhesives; it can also be copolymerized with vinyl chloride, acrylonitrile, butenoic acid, acrylic acid, and vinyl monomers to make polymer synthetic materials with different properties.

Vinyl acetate-acrylate latex paint can make the coating film have appropriate hardness and flexibility, and its solubility and adhesion.

Phenylacetate-acrylate latex paint is a low-cost matte latex paint for interior walls of ethylene-propylene. It is used in the decoration of residential rooms and as a general engineering paint.

I. Emergency Response to Leakage

Quickly evacuate personnel from the leaked contaminated area to a safe area and isolate them to strictly restrict access. Cut off the fire. It is recommended that emergency handlers wear self-contained positive-pressure respirators and fire protective clothing. Cut off the source of leakage as much as possible to prevent entry into restricted spaces such as sewers and flood drains. Small leaks: Adsorb or absorb with sand or other non-combustible materials. It can also be scrubbed with an emulsion made of a non-combustible dispersant, and the wash solution is diluted and put into a wastewater system. Large spills: build dikes or dig pits for containment. Spray water cools and dilutes vapors, protects site personnel, and dilutes leaks to non-combustibles. Transfer to

1. Addition of acetic acid and acetylene (condition: zinc acetate as catalyst, 170-250 ° C)

CHCH + CH3COOH > CH3COOCH = CH2

2. Direct oxidation of ethylene with acetic acid and oxygen (condition:

Vinyl acetate is a monomer that can be polymerized into polyvinyl acetate by itself, or it can be polymerized with other monomers to form

Vinyl acetate can react with most olefins or esters. For example, the addition of bromine to form a dibromide and the addition of hydrogen halide to produce 1-halo vinyl acetate are also the only methods for preparing this material, because there is no corresponding halogenated alcohol. Adding acetic acid under palladium catalysis can produce ethylene diacetate, CH3CH (OAc) 2. The latter can transesterify with many carboxylic acids. As an olefin, vinyl acetate can also undergo Diels-Alder reaction and 2 + 2 cycloaddition.
