US Classification:

568793, 568766, 568785, 568786, 568788, 568790, 568791

Abstract:

An alkylated hydroxyl-containing aromatic compound is produced by isomerizing a normal alpha-olefin having from about 16 to about 30 carbon atoms in the presence of a first solid, acidic catalyst capable of inducing both olefin isomerization and skeletal isomerization to produce a mixture of isomerized olefin, then alkylating an hydroxyl-containing aromatic compound with the mixture of isomerized olefins in the presence of a second solid, acidic catalyst. The first solid, acidic catalyst can be SM-3, MAPO-11, SAPO-11, SSZ-32, ZSM-23, MAPO-39, SAPO-39, ZSM-22, SSZ-20, ZSM-35, SUZ-4, NU-23, NU-87, natural ferrierite or synthetic ferrierite. The second solid, acidic catalyst can be a sulfonic acid anionic ion exchange resin catalyst or an acidic clay.
