| Calcium hypochlorite Usage And Synthesis |
| Description | Calcium hypochlorite (molecular formula: Ca (ClO)2) is a kind of inorganic compound. It appears as a white granular solid with chlorine odor. Though it is relatively stable and non-combustible, it will accelerate the burning of combustible materials. Sodium hypochlorite solid is generally not commercialized. Instead, it is highly soluble in water and can be formulated into various concentrations. The resulting sodium hypochlorite solutions appears as clear, green to yellow liquids. It has two major applications. One is sanitation. For this purpose, it is primarily used as bleaching agent or disinfectants to sanitize publish swimming pools as well as disinfect drinking water. It is also used in the disinfection of surfaces and equipment of kitchen and bathroom. Moreover, it can be used as algaecides, herbicide and laundry detergents. Another major application is in organic chemistry. It can act as a general oxidizing agent for the cleavage of glycols, keto acids to obtain fragmented aldehydes or carboxylic acid. It can also be used for the manufacture of chloroform. Calcium hypochlorite can be manufactured through the reaction between limes (Ca(OH)2) with chlorine gas to give various concentrations of products. Calcium hypochlorite is toxic. Its solution can emit toxic gases such as chlorine. Inhalation can lead to olfactory fatigue and irritation on the lung airway. It is also irritating to the skin and eye upon contact. Ingestion of it can cause vomiting and corrosive injury to the gastrointestinal tract. |

| Chemical Properties | Calcium hypochlorite, Ca(OCl)2.4H20, also known as calcium oxychloride, chlorinated lime, and bleach, is a deliquescent white powder used as a bleaching agent in the textile and pulp industries and as a disinfectant. It contains 60 to 65% available chlorine, |
| Chemical Properties | Calcium hypochlorite is a white powder, granule, or pellets with a strong chlorine-like odor. |
| Physical properties | White crystalline solid; density 2.35 g/cm3; decomposes when heated to 100°C; soluble in water and alcohol (with decomposition). |
| Uses | Bleaching powder is actually a mixture of calcium hypochlorite (Ca(ClO)2) and the basic chloride CaCl2, H2O with some slaked lime, Ca(OH)2. The product is generally called “bleaching powder”. It consists of a mixture of calcium chloride (CaCl2), calcium hypochlorite (Ca(OCl)2), and calcium chloride hypochlorite (CaCl(OCl)). Ca(ClO)2 is used in industrial wastewater treatment, sanitation and cleaning, epidemic prevention and household sanitation facilities, as well as for disinfection and sterilization of swimming pools, drinking water, cleaning vegetables, and sanitizing fishponds. Calcium hypochlorite has been used for bleaching of cotton, hemp, fiber, pulp and starch, disinfection of surfaces, and as a sterilant for water treatment. It has also been proposed as a solid fire extinguisher. |
| Uses | Bleaching of wood pulp, linen, cotton, straw, oils, soaps, and in laundering; oxidizer in calico printing to obtain white designs on a colored ground; destroying caterpillars; disinfecting drinking water, sewage, etc.; as a decontaminant for mustard gas and similar substances. |
