Patent ID: 7163972

Claim:
A method for producing a concentrated organophyllosilicate composition comprising: (a) mixing an aqueous slurry or filter cake comprising an organophyllosilicate having water molecules associated therewith with an oligomer capable of displacing the water molecules to separate at least a portion of the water from the organophyllosilicate, wherein the oligomer is selected from the group consisting of paraffin waxes, microcrystalline montan waxes, vegetable waxes, Fisher-Tropsch waxes, polypropylene waxes, polyethylene waxes, polyethylene glycol waxes, and combinations thereof, and the oligomer has a melting point of from about 10° C. to about 160° C.; and (b) removing at least a portion of the displaced water as a liquid from the slurry or filter cake to form a concentrated organophyllosilicate composition.
