Abstract
An organically modified clay is manufactured by a process wherein a clay having an exchangeable, cationic species therein is combined with a cationic organic material, subjected to a high confining pressure and mixed while under pressure so as to promote an ion exchange reaction whereby the cationic species is incorporated into the clay.
Claims7
A method of manufacturing an organically substituted clay comprising the steps of:
- premixing a substantially, non-slurried volume of clay having an exchangeable cationic species with a volume of a cationic organic material and, thereafter,
- subjecting said non-slurried mixture to a confining pressure of about 3,000 psi to at least about 8,000 psi while simultaneously further mixing said volumes so that at least some of the exchangeable cationic species in said clay are substituted by said cationic organic material and said mixture is warmed and plastic.
