摘要

An organo-clay is prepared by mixing a quaternary ammonium compound with an aqueous suspension of a smectite clay; thereafter subjecting the smectite clay quaternary ammonium compoundfwater 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.
