PROCESS FOR THE ALKYLATION OF HEAVY MONO-ALKYLATES OF SINGLE-RING AROMATIC HYDROCARBONS

摘要

A heavy mono-alkylated benzene, having a heavy-alkylate content of at least 20 weight percent, is produced by reacting a heavy mono-alkylated benzene with an olefin, having from 6 to 14 carbon atoms, at a pressure of up to about 10 bar s and a temperature of about from 100.degree. to 225.degree. C in the presence of an acidic catalyst. The acidic catalyst can be a molecular sieve or clay. The molecular sieve can be a natural or synthetic zeolite.
