Vinyl acetate

Common Name: Vinyl acetate Synonyms: Acetic acid vinyl ester | Vinyl acetate monomer | Acetic acid ethenyl ester | Acetic acid ethylene ester | Acetyl vinyl ester English Name: Vinyl acetate CAS No.: 108-05-4 EINECS: 203-545-4 Molecular Formula: C₄H₆O₂ Molecular Weight: 86.089 Density: 0.9±0.1 g/cm³ Boiling Point: 72.5±0.0 °C Melting Point: -93 °C Flash Point: -6.7±0.0 °C Appearance: Colorless liquid with a sweet, ether-like odor. Solubility: Slightly soluble in water; soluble in ethanol, benzene, and most organic solvents. Uses: 1. Used in the production of polyvinyl alcohol, coatings, adhesives, etc. 2. Vinyl acetate is a key raw material for producing synthetic fiber vinylon. It can undergo homopolymerization or copolymerization with other monomers to form polyvinyl alcohol, ethylene-vinyl acetate copolymer (EVA), vinyl acetate-vinyl chloride copolymer (EVC), vinyl acetate-acrylonitrile fibers, and vinyl acetate-acrylate copolymers. These products have significant industrial applications, widely used as adhesives, architectural coatings, textile sizing and finishing agents, paper strengthening agents, and in the production of safety glass. Vinyl acetate reacts with ethanol and bromine to produce bromoacetaldehyde diethyl acetal, an intermediate in the synthesis of the drug methimazole. 3. Used in resin and fiber synthesis, and as an intermediate for oil pour point depressants, thickeners, and adhesives. 4. A common intermediate for the production of polyvinyl alcohol, coatings, adhesives, etc.
