Vinyl Acetate Monomer Production Process

Vinyl acetate is the acetate ester of vinyl alcohol.

Vinyl acetate monomer production process.

Vinyl acetate monomer vam production and manufacturing process acetylene based technology was used first in the commercial production of vam with the gas phase process preferred to the liquid phase reaction. The users can investigate. The present invention relates to a process for forming vinyl acetate. The process comprises the step of providing a reaction mixture having an initial heat capacity.

The reaction mixture comprises acetic acid oxygen ethylene and optionally water. 10 vinyl acetate monomer process 10 1 basis of design the vinyl acetate monomer vam is large scale commodity chemical mostly used in manufacturing polyvinyl acetate the basic ingredient in water soluble acrylic paints. A simulation of a vinyl acetate monomer vam process design was developed and compared with the work of luyben and tyreus 1998. This plant model enables the users to experience realistic plant operation since it reflects the real plant characteristics and practical problems on the basis of experienced practitioners opinions.

Ethylene is now the preferred feedstock for vam vinyl acetate monomer largely replacing the earlier acetylene based process. 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. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. The vam is recovered by condensation and scrubbing and is then purified by distillation.

More importantly the plant model provides a new benchmark problem. Since vinyl alcohol is highly unstable with respect to acetaldehyde the preparation of vinyl acetate is more complex than the synthesis of other acetate esters.
