Abstract: Polychloroisocyanuric acids are produced by the reaction of monoalkali metal cyanurate with hypochlorous acid and a chlorinecontaining compound selected from the group consisting of chlorine and chlorine octahydrate where the molar ratio of chlorine-containing compound to monoalkali metal cyanurate is at least 1:1. Where an excess of chlorine-containing compound is used, this excess is employed to remove any gaseous by-products such as nitrogen trichloride, which may be formed during the reaction. This excess containing gaseous by-products is reacted with an alkali metal compound to convert the chlorine present to an alkali metal hypochlorite, which is further reaction to form hypochlorous acid. The hypochlorous acid can be used in the chlorination reaction. Reaction conditions include a temperature range of from -5* to 45*C. and a pH of 3 to 4.5.

Abstract translation: 多氯异氰脲酸是通过单碱金属氰脲酸酯与次氯酸和选自氯和氯八水合物的含氯化合物反应制备的，其中含氯化合物与单碱金属氰尿酸酯的摩尔比至少为1:1。 当使用过量的含氯化合物时，该过量用于除去可能在反应期间形成的任何气态副产物如三氯化氮。 含有气态副产物的过量与碱金属化合物反应，将存在的氯转化为碱金属次氯酸盐，进一步反应形成次氯酸。 次氯酸可用于氯化反应。 反应条件包括-5至45℃的温度范围和3至4.5的pH。
