METHOD OF PREPARING GRANULATED SYNTHETIC ZEOLITE-CONTAINING SYNTHETIC DETERGENT COMPONENT Russian patent published in 2004 - IPC

Abstract RU 2230779 C1

FIELD: synthetic detergents.

SUBSTANCE: concentrated sodium silicate and sodium aluminate solutions are mixed at silica-to-alumina molar ratio 2.0-2.5. Mixture is crystallized at 60-80^оС and stirred fro 0.4-6.0 h. Part of mother solution is separated from zeolite and suspension of zeolite in the rest of mother solution is diluted with water to return initial concentration and subjected to spray drying in flue gas flow.

EFFECT: achieved balanced chemical composition of zeolite-containing synthetic detergent component, which may be introduced into any synthetic detergent formulation.
