1. THE PROCESS OF PRODUCING POTASSIUM DICHLOROISOCYANURATE WHICH COMPRISES:

(A) INTRODUCING AN AQUEOUS POTASSIUM CARBONATE SOLUTION AND AN AQUEOUS STREAM OF DICHLOROISCYANURIC ACID SLURRY IN PROPORTIONS TO PRODUCE A REACTION MIXTURE HAVING A MOL RATIO OF DICHLOROISOCYNANURIC ACID TO POTASSIUM CARBONATE WITHIN THE RANGE OF FROM 1.2 RO 2.1, INTO A GENERALLY HORIZONTALLY DISPOSED, LONGITUDINALLY ELONGATED REACTION ZONE HAVING A LOWER PORTION FOR FLOW OF LIQUID REACTION MIXTURE THERETHROUGH AND HAVING CONTIGUOUS TO SAID LOWER PORTION AN UPPER GAS-RECEIVING PORTION, BOTH OF SAID PORTIONS EXTENDING FOR SUBSTANTIALLY THE FULL LENGTH OF SAID REACTION ZONE;

(B) FLOWING THE RESULTANT MIXTURE THROUGH THE LOWER PORTION OF SAID REACTION ZONE WHILE AGITATING THIS MIXTURE, AND MAINTAINING IT AT A TEMPERATURE WITIN THE RANGE OF FROM 5*C. TO 75*C.;
