Vinyl Acetate Production

Reaction zone 102 comprises reactor 106 and vaporizer 110.

Vinyl acetate production. Acetylene based technology was used first in the commercial production of vam with the gas phase process preferred to the liquid phase reaction. The vinyl acetate industry is an oligopoly that is a market with a limited number of producers because of the high market entry barriers of high capital costs and limited process technologies. The chinese government has increased public spending on transportation infrastructure. Vinyl acetate 108 05 4 hazard summary vinyl acetate is primarily used as a monomer in the production of polyvinyl acetate and polyvinyl alcohol.

The method comprises reacting ethylene acetic acid and an oxygen containing gas in the presence of a catalyst in a reactor to produce vinyl acetate measuring the concentration of a component involved in or associated with the reaction and or any of the subsequent steps by raman spectroscopic analysis and adjusting. As vinyl acetate is widely used in the production of paints and coatings adhesives and packaging materials. Acute short term inhalation exposure of workers to vinyl acetate has resulted in eye irritation and upper respiratory tract irritation. Globalization continues with production capacity being added in mainland china.

With china being a major player in these markets the demand for vinyl acetate is expected to grow during the forecast period. The following pie chart shows world consumption of vinyl acetate. 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 c4h6o2 cid 7904 structure chemical names physical and chemical properties classification patents literature biological activities safety.

For production an acetate is first nickel plated and the plating is removed to create a negative image known as a father. Disclosed is a method for controlling a vinyl acetate production process. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. The average list price for 2008 was 1600 tonne.

Ethylene has now become the preferred feedstock with the gas phase route used due problems of corrosion and byproduct. A genuine beatles acetate. Vinyl acetate production process 100 comprises reaction zone 102 and separation zone 104.
