Calcium hypochlorite

차아염소산 칼슘 C화학적 특성, 용도, 생산

화학적 성질

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,

화학적 성질

Calcium hypochlorite is a white powder, granule, or pellets with a strong chlorine-like odor.


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.


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.

제조 방법

Calcium hypochlorite is manufactured by two main processes, the socalled “calcium process” and the “sodium process”. These are essentially the same as described for the Mg(ClO)2 salt method given above except that a sodium hypochlorite salt is used in one


A white solid that can be regarded as a mixture of calcium chlorate(I) (calcium hypochlorite), calcium chloride, and calcium hydroxide. It is prepared on a large scale by passing a current of chlorine through a tilted cylinder down which is passed calcium hydroxide. Bleaching powder has been used for bleaching paper pulps and fabrics and for sterilizing water. Its bleaching power arises from the formation, in the presence of air containing carbon dioxide, of the oxidizing agent chloric(I) acid (hypochlorous acid, HClO):
Ca(ClO)2.Ca(OH)2.CaCl2 + 2CO2
2CaCO3 + CaCl2 + 2HClO.

화학 반응

As strong oxidant, calcium hypochlorite may react with vigor in combination with carbon compounds, and combination with finely divided carbon particles forms an explosive mixture. Reaction with acetylene leads to creation of explosive chloroacetylenes. Contact with organic matter, oil, hydrocarbons and alcohols such as methanol or ethanol may cause a violent explosion. Reaction with nitromethane causes a delayed violent reaction. Organic sulfur compounds such as sulfides react by self-ignition and explosion. Iron oxide in metal containers catalyze oxygen-evolving decomposition of the oxidant.

일반 설명

Calcium hypochlorite, hydrated is a white granular solid or tablets compressed from the granules having an odor of chlorine. Calcium hypochlorite is noncombustible, but Calcium hypochlorite will accelerate the burning of combustible materials. Calcium hypochlorite is decomposed by water with evolution of chlorine gas and heat. Prolonged exposure to fire or heat may result in the vigorous decomposition of the material and rupture of the container. Material containing less than 39% available chlorine may undergo reactions as described above though Calcium hypochlorite may take longer to initiate, and the resulting reactions may not be as vigorous. Calcium hypochlorite is used for water purification, disinfectant for swimming pools, for bleaching paper and textiles, and for many other uses.

반응 프로필

CALCIUM HYPOCHLORITE is a powerful oxidizing agent, particularly in the presence of water or at higher temperature as Calcium hypochlorite decomposes to release oxygen and chlorine gases. As strong oxidant Calcium hypochlorite may react with vigor in combination with carbon, especially finely divided is explosive; acetylene, leads to creation of explosive chloroacetylenes; organic matter, oil, hydrocarbons; alcohols may cause explosion, methanol, ethanol, etc.; nitromethane caused delayed violent reaction; organic sulfur compounds, sulfides tend toward ignition and sometimes explosion; with iron oxide in metal containers catalyze oxygen evolving decomposition of the oxidant. Calcium hypochlorite forms highly explosive NCl3 on contact with urea. Produces highly toxic gaseous chlorine gas when heated or on contact with acids [Sax, 9th ed., 1996, p. 1905]. Mixture of damp sulfur with hypochlorite caused a violent reaction, that ejected molten sulfur, Chem Eng. News, 1965, 46(29), 6.


Dangerous fire risk in contact with organic materials.


Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.


These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.

공업 용도

Calcium hypochlorite Ca(OCl)2 can be found in swimming pool disinfectants, in bleaching agents, in deodorants and in fungicides.

비 호환성

A powerful oxidizer. Decomposes in heat or sunlight; becomes explosive above 100C/212F. Incompatible with strong acids; water and other forms of moisture, reducing agents; combustible materials; all other chemicals, especially acetylene, aniline and all other amines, anthracene, carbon tetrachloride, iron oxide, manganese oxide, mercaptans, diethylene glycol monomethyl ether, nitromethane, organic matter; organic sulfides, phenol, 1-propanethiol, propyl mercaptan, sulfur, turpentine, organic sulfur compounds. Attacks various metals, releasing flammable hydrogen gas.

폐기물 처리

Dissolve the material in water and add to a large volume of concentrated reducing agent solution, then acidify the mixture with H2SO4. When reduction is complete, soda ash is added to make the solution alkaline. The alkaline liquid is decanted from any sludge produced, neutralized, and diluted before discharge to a sewer or stream. The sludge is landfilled
