Remarks:
Sodium Hypo Chlorite
Electrolysis Process ( Pure & Concentrated )
This is an improved version of this method, known as the Hooker process, In the process, sodium hypochlorite (NaClO) formed when chlorine is passed into cold and dilute sodium salt solution. It is prepared with minimal separation between the anode and the cathode .The solution must be kept below 40 °C (by cooling coils) to prevent the undesired formation of sodium chlorate and to keep chlorine concentration up to 15%.
Chloro Alkali process ( Chlorine value is less )
E. S. Smith patented a method of sodium hypochlorite production involving electrolysis of brine to produce sodium hydroxide and chlorine gas, which then mixed to form sodium hypochlorite. This is known as the chloralkali process. Both electric power and brine solution were in cheap supply at the time, and various enterprising marketers took advantage of the situation to satisfy the market's demand for sodium hypochlorite. Bottled solutions of sodium hypochlorite were sold under numerous trade names.
Bye Products
This is bye products of HEAVY / Metal industries. During treatment of main products, huge quantities of SOD. HYPO Chlorite produce, with mixture of many unwanted toxic impurities . This is completely waste of the plant , but sold by traders to satisfy market demands.
