ABSTRACT:
An improved process for production of phenylalkylsulfonate compounds whereby the proportion of the 2-alkylphenylsulfonate isomer is reduced relative to the higher numbered isomers thereof (3-alkyl; 4-alkyl; etc.). After alkylation of aromatic compounds to produce a mixture of alkylbenzenes, the 2-alkylbenzene isomer is selectively cracked to lower boiling products, leaving the higher numbered isomers substantially unreacted. Subsequent sulfonation results in alkylphenylsulfonate derivatives having improved detergency properties.
