An economical, industrial and ecologically-sound process for producing high test hypochlorite and a calcium chloride aqueous solution comprising the steps of (a) preparing milk of lime, (b) chlorinating the milk of lime to crystallize calcium hypochlorite dihydrate in the presence of the prismatic calcium hypochlorite dihydrate seed crystals having a specific habit to prepare a slurry of ...
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 un-separated chloralkali process.
Sodium hypochlorite . From calcium hypochlorite Another is the only large-scale 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
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).
Abstract: A continuous integrated process for the production of neutral calcium hypochlorite in which crystals of by-product sodium chloride are more easily separated from the calcium hypochlorite product is described. The process includes diluting an aqueous slurry of sodium hydroxide, lime and bleach mother liquor with aqueous salt solution ...
Tony K.M. Shing, in Comprehensive Organic Synthesis, 1991. 5.3.5 Calcium Hypochlorite. Calcium hypochlorite, Ca(OCl) 2, an inexpensive and easily stored oxidant, can be used to cleave α-glycols to the corresponding carbonyl compounds.α-Diones, α-hydroxy ketones and α-hydroxy and α-keto acids are also oxidatively fragmented. 19 Aldehydic products are further oxidized to acids with an ...
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 ...
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.
