Abstract
An organoclay is prepared by mixing a quaternary ammonium compound with an aqueous suspension of a smectite clay in proportions such that there are present from 75 to 110 milliequivalents of quaternary ammonium cation per 100 g of dry smectite clay, thereafter subjecting the smectite clay/quaternary ammonium compound/water mixture to high shear mixing for a time sufficient to dissipate in the mixture at least 100 KJ of energy per kg. of dry solids in the mixture; and then dewatering the product thus obtained.
