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.
Claims12
A process for forming a kaolin-potassium acetate intercalation complex, comprising:
- mixing kaolin clay particles, potassium acetate and water until a substantially homogeneous mixture is obtained,
- wherein potassium acetate is present in the mixture in an amount from about 10 to 75% by weight, based on the weight of the kaolin clay particles,
- and water is present in the mixture in an amount from about 5 to 50% by weight, based on the weight of the potassium acetate.
