Abstract
The present invention is a process for producing phenyl-alkanes at alkylation conditions in the presence of a zeolite having an NES zeolite structure type, such as NU-87. This invention produces phenyl-alkanes having lightly branched aliphatic alkyl groups which are used to produce modified alkylbenzene sulfonates that have improved cleaning effectiveness in hard and/or cold water while also having biodegradability comparable to that of linear alkylbenzene sulfonates.
