Continuous Process For Making Calcium Hypochlorite
US Patent:
4364917, Dec 21, 1982
Filed:
Feb 26, 1982
Appl. No.:
6/352543
Inventors:
Herman H. Tiedemann - Texas City TX
Gilbert Thibault - Coquitlam, CA

Assignee:
C-I-L Inc. - North York
International Classification:
C01B 1106
US Classification:
423474
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.
Making Calcium Hypochlorite From Impure Lime
US Patent:
4374115, Feb 15, 1983
Filed:
Aug 25, 1981
Appl. No.:
6/296155
Inventors:
Herman H. Tiedemann - Texas City TX
Assignee:
Chemetics International Ltd. - North York
International Classification:
C01B 1106
US Classification:
423474
Abstract:
Calcium hypochlorite is made by passing chlorine through an aqueous solution of alkali metal hydroxides containing suspended particles of calcium hydroxide, said alkali metal hydroxides consisting of sodium hydroxide and an hydroxide of an alkali metal having an atomic weight higher than that of sodium.
