Technology Profile: Calcium Hypochlorite Production

01/11/2017 Calcium hypochlorite, Ca(OCl)2, is among the few metal hypochlorites that is stable enough to be produced as a solid salt. Because of this fact, it is the main bleaching agent produced commercially as a solid (sometimes referred to as bleach powder). Figure 1.
