  • Alkylation of aromatic hydrocarbons
    Patent number: 5157158
    Abstract: A process is described for the alkylation of benzene (in general, aromatic hydrocarbons), with C.sub.2 -C.sub.20 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.
    Type: Grant
    Filed: August 15, 1991
    Date of Patent: October 20, 1992
    Assignee: Petroquimica Espanola, S.A. Petresa
    Inventors: Jose L. Berna Tejero, Alfonso Moreno Danvila
