Vinyl Acetate Monomer Production Process

Vinyl acetate is the acetate ester of vinyl alcohol.

Vinyl acetate monomer production process.

Abstract a rigorous dynamic plant model of a vinyl acetate monomer vam production was developed. The vam is recovered by condensation and scrubbing and is then purified by distillation. The reaction mixture comprises acetic acid oxygen ethylene and optionally water. The present invention relates to a process for forming vinyl acetate.

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. 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 users can investigate. 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.

A simulation of a vinyl acetate monomer vam process design was developed and compared with the work of luyben and tyreus 1998. 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 process comprises the step of providing a reaction mixture having an initial heat capacity. Vam is usually produced by the catalysed vapour phase reaction of acetic acid with ethylene and oxygen in a fixed bed tubular reactor using a supported noble metal catalyst.

The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. Two incremental changes were made to the two main control.
