Vinyl acetate monomer production.

Vinyl acetate monomer vam production and manufacturing process. Vinyl acetate monomer vam production which is based on reacting acetic acid aa with ethylene and oxygen dimian and bildea 2008. Vinyl acetate is an industrial chemical that is produced in large amounts in the united states. Acute short term inhalation exposure of workers to vinyl acetate has resulted in eye irritation and upper respiratory tract irritation.

Acetylene based technology was used first in the commercial production of vam with the gas phase process preferred to the liquid phase reaction. It is very flammable and may be ignited by heat sparks or flames. The following are the primary and side reactions. Vam can be polymerized in mass solution suspension or emulsion.

Vinyl acetate is used to make other industrial chemicals. 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. 2009 with production capacity of 330 000 metric tons per annum mtpa. Vinyl acetate monomer is colorless liquid produced by international vinyl acetate company ivc an affiliate of sipchem from nov.

The main production method for vinyl acetate monomer is the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. It is a clear colorless liquid with a sweet fruity smell. The vam is recovered by condensation and scrubbing and is then purified by distillation. Ethylene has now become the preferred feedstock with the gas phase route used due problems of corrosion and byproduct.

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 is a high volume building block chemical used in the manufacture of polyvinyl acetate or vinyl acetate copolymers. When handled properly vam can be stored transported and otherwise managed safely.
