SUPERALKALINIZED ISOMERIZED LINEAR ALKYLARYL SULFONATES OF ALKALINE EARTH METALS, USEFUL AS DETERGENT/DISPERSANT ADDITIVES FOR LUBRICATING OILS, AND PROCESSES FOR THEIR PREPARATION AND INTERMEDIATE ALKYLARYL HYDROCARBON

摘要

A superalkalinized alkylaryl sulfonate of alkaline earth metal is disclosed. The aryl radical is either a tolyl, xylyl, o xylyl, ethyl phenyl, or cumenyl radical. The alkyl chain is a linear chain that contains between 14 and 40 carbon atoms, and the aryl sulfonate radical of alkaline earth metal is fixed, in a molar proportion comprised between 0 and 13% in positions 1 or 2 of the linear alkyl chain.
