DISPROPORTIONATION OF ALKENES

摘要

A catalytic process for the disproportionation of alkenes in a distillation column reactor, whereby high conversion and selectivity are simultaneously achieved. The process comprises contacting at least one alkene with a catalyst in a distillation column reactor under such reaction fractionation conditions that there are formed products of the disproportionation of at least one of said alkenes and such that the combined yield of said products is at least 65 mole percent. By use of the distillation column reactor, the disproportionation and the separation of products are advantageously conducted simultaneously. Conventional processes for the disproportionation of alkenes may be operated at temperatures as high as 500.degree.C but are unable to achieve simultaneous high conversion and high selectivity. These conventional processes are conducted in a fixed bed reactor. In contrast, the process of the present invention is capable of obtaining simultaneous high conversion and high selectivity. 30,442B-F
