Abstract
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.
