Abstract
A process for preparing an alkylaryl sulfonate comprising (a) reacting at least one meta-xylene compound with olefin or a mixture of olefins having from about 10 to about 20 carbon atoms, in the presence of an acid catalyst, wherein the resulting product comprises no more than 40 weight percent of 1-alkyl-2,4 dimethylsubstituted aromatic compound and at least about 60 weight percent of 1-alkyl-3,5 dimethyl substituted aromatic compound; (b) sulfonating the product of (a); and (c) neutralizing the product of (b) with a source of alkali or alkaline earth metal or ammonia.
