Abstract
A method is provided for producing vinyl chloride monomer from methyl chloride and methylene chloride. In the method, methyl chloride is reacted with methylene chloride in the vapor phase in the presence of a catalyst to produce vinyl chloride and hydrogen chloride. The reaction temperature is in the range of from about 300° C. to 500° C. The catalyst is selected from the group alumina gel, gamma-alumina, zinc chloride on active alumina, silica-alumina, zeolite, and silicon-aluminum-phosphorus oxide.

A method for producing vinyl chloride comprising the reaction of methyl chloride with methylene chloride in the vapor phase in the presence of a catalyst selected from the group consisting of alumina gel, gamma-alumina, zinc chloride on active alumina, silica-alumina, zeolite, and silicon-aluminum-phosphorus oxide to produce said vinyl chloride and a byproduct of hydrogen chloride, wherein the molar ratio of said methyl chloride and said methylene chloride is 1 to 1.
A method for producing vinyl chloride monomer, comprising:
- reacting methyl chloride and methylene chloride in the presence of a catalyst to produce a reactor effluent;
- quenching said reactor effluent to produce a vapor stream and a liquid stream;
- and
- separating said liquid stream into a vinyl chloride monomer stream and a heavy ends stream.
