Abstract:
A process for preparing (branched-alkyl) arylsulfonates comprising:hydrocracking and hydroisomerizing a paraffinic wax to produce an isoparaffinic composition comprising 0.5% or less quaternary aliphatic carbon atoms, said isoparaffinic composition comprising paraffins having a carbon number of from about 7 to about 18, at least a portion of said paraffins being branched paraffins comprising an average number of branches per paraffin molecule of at least 0.5, said branches comprising a first number of methyl branches and optionally a second number of ethyl branches; exposing said isoparaffinic composition to a dehydrogenation catalyst in an amount and under dehydrogenation conditions effective to and unconverted paraffins, said branched olefins comprising 0.5% or less quaternary aliphatic carbon atoms; contacting said branched olefins with an aromatic hydrocarbon in the presence of a quantity of an alkylation catalyst under alkylation conditions effective to alkylate said aromatic hydrocarbon, producing branched alkyl aromatic hydrocarbons comprising 05% or less quaternary aliphatic carbon atoms; sulfonating said branched alkyl aromatic hydrocarbons.
