Vinyl Acetate Monomer Production

It is very flammable and may be ignited by heat sparks or flames.

Vinyl acetate monomer production.

Vinyl acetate monomer vam is a high volume building block chemical used in the manufacture of polyvinyl acetate or vinyl acetate copolymers. Ethylene has now become the preferred feedstock with the gas phase route used due problems of corrosion and byproduct. The following are the primary and side reactions. The vam is recovered by condensation and scrubbing and is then purified by distillation.

These polymers are the base for many industrial and consumer products as well as for other polymers. When handled properly vam can be stored transported and otherwise managed safely. Vinyl acetate monomer is colorless liquid produced by international vinyl acetate company ivc an affiliate of sipchem from nov. Vinyl acetate monomer vam is used for the production of polymer emulsions of various types which are base resins for water based paints adhesives paper coatings and textile finishes.

It is a clear colorless liquid with a sweet fruity smell. Vinyl acetate 108 05 4 hazard summary vinyl acetate is primarily used as a monomer in the production of polyvinyl acetate and polyvinyl alcohol. Vam can be polymerized in mass solution suspension or emulsion. Acetylene based technology was used first in the commercial production of vam with the gas phase process preferred to the liquid phase reaction.

The worldwide production capacity of vinyl acetate was estimated at 6 969 000 tonnes year in 2007 with most capacity concentrated in the united states 1 585 000 all in texas china 1 261 000 japan 725 000 and taiwan 650 000. Vinyl acetate monomer vam production which is based on reacting acetic acid aa with ethylene and oxygen dimian and bildea 2008. Acute short term inhalation exposure of workers to vinyl acetate has resulted in eye irritation and upper respiratory tract irritation. The worldwide production capacity of vinyl acetate was estimated at 6 969 000 tonnes year in 2007 with most capacity concentrated in the united states 1 585 000 all in texas china 1 261 000 japan 725 000 and taiwan 650 000.

The average list price for 2008 was 1600 tonne. Vinyl acetate is an industrial chemical that is produced in large amounts in the united states. 2009 with production capacity of 330 000 metric tons per annum mtpa.
