VISCOSITY INCREASING ADDITIVE FOR NON-AQUEOUS FLUID SYSTEMS

摘要

An organoclay rheological additive for non-aqueous fluid systems comprising an organophilic clay comprising the reaction product of a smectite-type clay having a cation exchange capacity of at least 75 milliequivalents per 100 grams of clay and methyl benzyl dialkyl ammonium compound or dibenzyl dialkyl ammonium compound wherein the alkyl groups contain specific amounts of 8 to 22 carbon atoms and the amount of said ammonium compound reacted with said clay being from 100 to 130 milliequivalents per 100 grams of clay based upon 100? active clay.
