ABSTRACT:
A process for making calcium hypochlorite from caustic soda calcium hydroxide and chlorine by feeding to a stirred reactor an aqueous solution of the total required amount of caustic soda and an aqueous suspension of up to 80% by weight of the total required amount of calcium hydroxide, passing chlorine through the mixture until a redox potential of 650 to 800 mV is reached and while continuing chlorination adding the remaining of the calcium hydroxide at such rate with respect to chlorine that redox potential gradually increases to between 850 and 950 mV. This process prevents thickening and caking which are a recognized problem with conventional batch processes.
