SOLID DISPERSANT IN NONAQUEOUS SYSTEM

摘要

PURPOSE:To enhance the dispersion stability of solid particles in a nonaqueous system by incorporating a mixture of the alkanol amide of a fatty acid or its addition product with an alkylene oxide and a phosphoric ester or its salt into the titled dispersant as an effective component. CONSTITUTION:The alkanol amide of a fatty acid or its addition product with an alkylene oxide is mixed with a monoester or a diester expressed by formula I (R shows 1-30C alkyl and alkenyl group and a 1-30C alkylphenyl having an alkyl group, AO represents and alkylene oxide such as ethylene oxide, propylene oxide and butylene oxide, (n) shows the number of mols of added alkylene oxide and is 0-100 and K stands for 1 or 2). The mixture is incorporated as an effective component to prepare a solid dispersant in a nonaqueous system.
