ABSTRACT:
Chloroisocyanuric acids are made by reacting an aqueous suspension of cyanuric acid while stirring with an alkali metal compound in the presence of chlorine gas between 0.degree. and 40.degree. C. at a pH of less than 7. More particularly, the reaction is effected in a system gastightly sealed with respect to the outside; a chlorine gas atmosphere with pressure of more than 500 millibars is established above the continuously renewed (by agitation) surface of the cyanuric acid suspension, and the pressure is maintained; the alkali metal compound is an alkali metal hydroxide solution which is added to the cyanuric acid suspension at a rate sufficient for the resulting reaction mixture to always present a pH of less than 7.
