Abstract

A process for intercalating potassium acetate molecules in kaolin clay particles to achieve delamination has been developed by mixing kaolin clay particles, potassium acetate and water. A maximum intercalation, and hence a maximum degree of delamination, can be achieved with potassium acetate levels between 10% and 75% by weight, based on the weight of kaolin clay particles, and 5% and 50% water by weight, based on the weight of potassium acetate.
