  • Patent number: 8916726
    Abstract: Disclosed is a method for improving filtration in the preparation of an alkaline earth metal alkyltoluene sulfonate concentrate by selectively controlling the meta, ortho, para isomer distribution of the alkyl group of the alkyltoluene produced by the process comprising alkylating toluene with at least one isomerized normal alpha olefin, having from about 18 to about 30 carbon atoms and having from 20% to 100% branching in an alkylation process which includes monitoring % isomer formation and adjusting an alkylation process parameter in order to provide a target specified isomer content of less than 38% meta-isomer content; and thereafter sulfonating and neutralizing to produce a low base number sulfonated alkyltoluene concentrate having a Base Number of about 2 to 60 (ASTM D 2896).

  • Patent number: 8293698
    Abstract: Disclosed are detergent mixtures of alkyl aryl sulfonates of alkaline earth metals derived from linear olefins having a relatively high aryl ring attached on positions 1 or 2 or the linear alkyl chains. The compositions contain a relatively high amount of 1 or 2 tolyl or xylyl isomer of the linear alkylaryl sulfonate and employ a heavy alkyl benzene sulfonate derived from linear olefins and exhibit improved stability and compatibility.
