ABSTRACT:
An improvement is disclosed for use in the process wherein an organophilic clay is manufactured by reacting a smectite-type clay with a higher alkyl-containing quaternary ammonium compound. According to the improvement of the invention, the gelling properties of the resulting organoclay are enhanced, by subjecting the clay as a pumpable slurry, to high-speed fluid shear, prior to the reaction thereof with the ammonium compound.
