Surfactant washing of polychloroisocyanuric acids

摘要

A process for the production of a polychloroisocyanuric acid filter cake having reduced moisture and salt content leading to quicker drying and a purer product is disclosed. Such a result is achieved by the addition of between about 50 and about 500 ppm of a suitable surfactant wetting agent to the water used to wash the cake after it is filtered from the reaction mass. Preferred surfactant wetting agents are alkoxylated alkyl alcohols and sodium dialkyl sulfosuccinates.
