Calcium hypochlorite Chemical Properties,Uses,Production


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.


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.


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.

General Description

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.

Reactivity Profile

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.

Health Hazard

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.

Fire Hazard

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.

Industrial uses

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

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy


UN1748 Calcium hypochlorite, dry or Calcium hypochlorite mixtures dry with .39% available chlorine (8.8% available oxygen), Hazard Class: 5.1; Labels: 5.1- Oxidizer. UN2208 Calcium hypochlorite mixtures, dry, with .10% but not .39% available chlorine, Hazard Class: 5.1; Labels: 5.1-Oxidizer. UN2880 Calcium hypochlorite, hydrated or Calcium hypochlorite, hydrated mixtures, with not ,5.5% but not .16% water, Hazard Class: 5.1; Labels: 5.1-Oxidizer


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.

Waste Disposal

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
