Alkylation of alkanes with mixtures of alkenes and alkyl halides |
| abstract |
Although alkenes commonly are used to alkylate alkanes using various solid acid catalysts, the process is severely hampered by short catalyst lifetimes attending substantial alkene oligomerization. This problem can be avoided by using an alkene-alkyl chloride mixture as the alkylating agent. Thus, alkylation of isobutane by a butyl chloride/butene mixture at a molar ratio of 1:3 in the presence of an AlCl 3 -type Friedel-Crafts catalyst at 30° C. maintains at least an 80% conversion of (alkene and alkyl chloride) for almost twice as long as is the case for a 1:19 molar ratio of butyl chloride/butene. |
