Patent number: 4382895Abstract: A process for the production of petroleum sulfonates from lubricating oil extract fractions wherein a primary extract-solvent mixture, preferably substantially free from water, is cooled to a temperature at least 25.degree. C. below the extraction temperature to form two immiscible liquid phases comprising a secondary extract phase which is richer in aromatic hydrocarbons than the primary extract and a secondary raffinate phase which is poorer in aromatics than the primary extract. The secondary raffinate is sulfonated and the unsulfonated fraction returned to the separations process.The process results in improved yields of petroleum sulfonates with lowered SO.sub.3 consumption and less by-product sludge than conventional processes in which the entire extract fraction is sulfonated.Type: GrantFiled: July 20, 1981Date of Patent: May 10, 1983Assignee: Texaco Inc.Inventors: Edward L.

Patent number: 4138444Abstract: Isobutane is self-alkylated to an alkylate composition having high octane components including trimethylpentanes in the presence of a solid catalyst and a minor amount of a C.sub.5 and higher olefin. The self-alkylation process utilizes a chlorided alumina catalyst having from about 4 to 15 weight percent chlorine. The olefins of choice employed in the isobutane self-alkylation reaction are isoolefins having 6 or 7 carbons. The isobutane may be derived from the isomerization of n-butane and the isomerization process may be integrated with the self-alkylation process.Type: GrantFiled: November 3, 1977Date of Patent: February 6, 1979Assignee: Texaco Inc.Inventors: Sheldon Herbstman, Edward L.
