  • Method for the preparation of low overbased alkyltoluene sulfonate
    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).
    Type: Grant
    Filed: March 20, 2011
    Date of Patent: December 23, 2014
    Assignee: Chevron Oronite Company LLC
