Katalytisches Verfahren zur Alkylierung von aromatischen Kohlenwasserstoffen in einem Fest-Bett

摘要

A process is described for the alkylation of benzene (in general, aromatic hydrocarbons), with C2-C20 monoolefins in the presence of an aluminum-magnesium silicate catalyst, to give linear alkylbenzenes of detergent range, basic product in the manufacture of biodegradable detergents. The process is continuously carried out in a fixed bed, the alkylation taking place in a liquid phase. The alkylation catalyst is mainly made up of aluminum silicate and/or magnesium silicate and is conveniently modified to improve its activity and attain an adequate yield and selectivity in the alkylation for the desired product.
