Calcium Hypochlorite Manufacture via Sodium Method

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).

. The compound is employed as a catalyst in the manufacture of a multitude of organic chemicals produced by several different reaction mechanisms, including isomerization, alkylation and polymerization.

Technology Description

This simplified process flow diagram depicts a typical, so-called “sodium process” for the production of calcium hypochlorite (70 wt.%) from slaked lime, sodium hydroxide and chlorine.
