Abstract
A process for the continuous preparation of a slurry of calcium hypochlorite wherein a solution of sodium hydroxide is fed to one end of an elongated tubular reaction and a calcium hydroxide slurry and chlorine are introduced through a number of injection sites along the length of the reactor. The redox potential of the reaction mixture at any injection site must not be inferior to that at the immediately preceding site and must be in the range 900 to 950 mV at the exit end of the reactor. The process permits easy control of the reaction temperature and of the viscosity of the reaction mixture.
