May 04, 1982· The aforesaid Example demonstrates that admixture of sodium hydroxide in the salt nucleator of the described process with a slurry of dibasic calcium hypochlorite and aqueous salt solution saturated with calcium hypochlorite and sodium chloride results in the production of larger sodium chloride salt crystals than when such reactant streams are ...
Tianjin Kaifeng Chemical Co., Ltd. (Tianjin Donghai Chemical Factory) was established at the early of 1989 with an investment over RMB 10 millions. Years later, Kaifeng has become a Chinese specialized manufacturer of Calcium Hypochlorite and Bleaching Liquid.
This work is focus on the production of calcium hypochlorite, this was achieved by running chlorine gas into four sample bottles containing prepared solution of Ca(oH) at the same flow rate but at ...
Sodium Hypochlorite is commonly produced either through a batch process or through a continuous process. Sodium Hypochlorite Production Sodium Hypochlorite can be produced using either a batch production method, such as with the Powell Sodium Hypochlorite Batch System or in greater volumes using a continuous method.
This report presents the economics of Calcium Hypochlorite production from slaked lime and chlorine via a typical calcium process. In this process, slaked lime is hydrated and chlorinated. A mixture of Calcium Hypochlorite, calcium chloride, and calcium hydroxide (also known as bleaching powder) is obtained as the final product.

Apr 01, 2013· The process The chlorination of caustic soda to sodium hypochlorite is an exothermic reaction. The chemical production process depicted below is a widely used process, similar to the one employed by Solvay Chemicals (Brussels, Belgium; ), for example.
Production capacity of calcium hypochlorite in 1989–90 in countries for which data were available are presented in Table 2. Japanese production of sodium hypochlorite (12% solution) was 947 thousand tonnes in 1984, 954 in 1985, 996 in 1986, 972 in 1987 and 989 in 1988 (Anon., 1985; Ministry of International Trade and Industry, 1989).

Apr 08, 1980· A process for the production of a calcium hypochlorite composition which comprises reacting solid granular hydrated lime, a solid granular alkali metal hydroxide, and chlorine gas in the adsence of a liquid solvent medium to form a reaction mixture, agitating said reaction mixture and recovering a calcium hypochlorite composition having an available chlorine content of up to about 50 .
Sodium hypochlorite (NaOCl) is produced by direct reaction of chlorine gas with caustic soda solution from chloralkali process, producing a water solution at approx. 150 g/l concentration, commonly known as bleach, to be used for water treatment, for bleaching agent in .
The oxide is itself obtained by heating calcium carbonate minerals such as chalk or limestone. Tennant took out a patent for making bleaching powder in 1799. The previous year, he had patented a similar process for producing bleach liquor, a solution of calcium hypochlorite in water.
This process is widely used for the industrial production of sodium hypochlorite (NaClO) and calcium hypochlorite (Ca(ClO) 2). Cl 2 + 2 NaOH → NaCl + NaClO + H 2 O 2 Cl 2 + 2 Ca(OH) 2 → CaCl 2 + Ca(ClO) 2 + 2 H 2 O. Large amounts of sodium hypochlorite are also produced electrochemically via an unseparated chloralkali process.

KERN SD, develops tailormade solutions for the production "in situ" of 70% calcium hypochlorite from chlorine gas and sodium hydroxide. KERN SD systems are fully customisable in terms of production and concentration. The overall reaction of the process is: Ca(OH) 2+ 2 NaOH + 2 Cl
Calcium hypochlorite production process basically consists of hydrated lime reaction with gaseous chlorine, according to complete reaction: 2Ca (OH) 2 + 2 Cl 2 = Ca (OCl) 2 + CaCl 2 + 2 H 2 O Raw materials are hydrated lime and gaseous chlorine. An acqueous suspension of milk lime is fed to the first reactor, where the chlorination takes place.
This report presents the economics of Calcium Hypochlorite (70 wt%) production from slaked lime, sodium hydroxide and chlorine via a typical sodium process. In this process, chlorine is passed into a slurry of slaked lime and sodium hydroxide, generating calcium hypochlorite and sodium chloride.
Sodium hypochlorite . From calcium hypochlorite Another is the only largescale industrial method of sodium hypochlorite production In the process sodium hypochlorite (NaClO) and sodium chloride (NaCl) are formed when chlorine is passed into cold dilute sodium hydroxide solution Packaging and sale
