At one time chloroprene 2 chloro 1 3 butadiene an industrially important monomer was produced via the intermediacy of vinyl acetylene.

Acetylene to vinyl chloride.

In this process acetylene is dimerized to give vinyl acetylene which is then combined with hydrogen chloride to give 4 chloro 1 2 butadiene via 1 4 addition. A rate equation which well represented the data was developed from the following postulates. 2 1 vinyl chloride from acetylene the process that produces vinyl chloride from acetylene employs the use of a catalyst. We at probe economics wanted to know how much the playing field had changed and how competitive chinese polyvinyl chloride pvc production is considering the high capital and environmental costs of the carbide based also known as acetylene pvc process used predominantly in china.

Most of the time the catalyst used is mercuric chloride deposited on active carbon. The hazards of storing and shipping acetylene meant that the vinyl chloride facility needed to be located very close to the acetylene generating facility. Please select more than one item to compare.
