quantitative ion exchange process for the preparation of modified clays and its product

摘要

A quantitative ion exchange process for preparing modified clay is disclosed. Clay such as montmorillonite is converted (1) to an acid-free hydrogen-clay by use of an anion (hydroxide) exchange resin; or (2) to another cationic form such as lithium-clay by use of an anion (hydroxide) exchange resin and an equivalent amount of the exchanging cation.
