A process for preparing (branched-alkyl) arylsulphonates and a (branched-alkyl) arylsulphonate composition

摘要

A process for preparing branched alkyl aromatic hydrocarbons, which process comprises contacting branched olefins with an aromatic hydrocarbon under alkylating conditions, which branched olefins have been obtained by a process which comprises dehydrogenating an isoparaffinic composition comprising 0.5% or less quaternary aliphatic carbon atoms over a suitable catalyst, which isoparaffinic composition has been obtained by hydrocracking and hydroisomerisation of a paraffinic wax and which isoparaffinic composition comprises paraffins having a carbon number in the range of from 7 to 35, of which paraffins at least a portion of the molecules is branched, the average number of branches per paraffin molecule being 0.5 to 2.5 and the branching comprising methyl and optionally ethyl branches, said branched olefins comprising 0.5% or less quaternary aliphatic hydrocarbons, wherein the paraffinic wax is obtained in a Fischer Tropsch synthesis.
