A process for producing a chloroisocyanuric acid compound which comprises reacting cyanuric acid with a chlorinating agent consisting of an aqueous solution of hypochlorous acid substantially free of ionic impurities having a pH of less than about 2. The process produces chloroisocyanuric acid compounds with reduced volumes of effluent solutions and significantly reduced amounts of gas released during operation. The novel process for producing chloroisocyanuric acid compounds can employ solid forms of cyanuric acid as a reactant.

Process for producing chloroisocyanurate compounds with concentrated

A process is described for concentrating a dilute slurry of s-triazine compounds in a liquid phase which comprises:

Process for concentrating dilute slurries of cyanuric acid compounds

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.
