Process for the preparation of alkylbenzenes

摘要

A process for preparing alkylbenzenes, according to which benzene is reacted with an olefin (or mixture of olefins) in the presence of a suitable catalyst, according to the Friedel-Crafts reaction. The reactant which is reacted with the benzene is the product of the autocondensation of an olefin or a mixture of olefins, having a number of carbon atoms of between 10 and 15, whereby a mixture of both light and heavy alkylbenzenes is obtained, the heavy alkylbenzenes being useful for lubricating compositions.
