Usage

Chemical Description

Calcium hypochlorite is a white solid that is commonly used as a swimming pool disinfectant.

Description

Different sources of media describe the Description of 7778-54-3 differently. You can refer to the following data:
1. 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.
2. Calcium hypochlorite, is an oxysalt; it is a crystalline solid and an oxidizer that decomposes at 212°F (100°C). Calcium hypochlorite is a dangerous fire risk in contact with organic materials. It is also a common swimming pool chlorinator and decomposes in contact with water, releasing chlorine into the water. If a container of calcium hypochlorite becomes wet in storage, the result can be an exothermic reaction. If combustible materials are present, a fire may occur. The chlorine in the compound will be released by contact with the water and will then accelerate the combustion process. The four-digit UN identification number for dry mixtures with not less than 39% available chlorine (8.8% oxygen) is 1748; hydrated with not less than 5.5% and not more than 10% water, the number is 2880; mixtures that are dry, with not less than 10% but not more than 39% available chlorine, are numbered as 2208. The NFPA 704 designation for calcium hypochlorite is health 3, flammability 0, and reactivity 1. The white section at the bottom of the diamond has the prefix “oxy,” indicating an oxidizer. The primary uses are as a bleaching agent, a swimming pool disinfectant, a fungicide, in potable-water purification, and as a deodorant.

Chemical Properties

Different sources of media describe the Chemical Properties of 7778-54-3 differently. You can refer to the following data:
1. 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,
2. 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

Different sources of media describe the Uses of 7778-54-3 differently. You can refer to the following data:
1. Deodorant, oxidizing agent, bleaching agentCalcium hypochlorite is used for swimming pool sanitation and other water treatment plants. It is also used to disinfect drinking water, equipments in the industry and surfaces and equipments in kitchens. Further, it is used to bleach textiles and paper. It is also employed in bathroom cleaners and laundry detergents. It is used as an oxidizing agent in organic chemistry. It is involved in the cleavage of glycols, alfa-hydroxy carboxylic acids and keto acids to yield fragmented aldehydes or carboxylic acids respectively. It plays an important role in the haloform reaction to prepare chloroform.
2. 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.
3. 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.

Definition

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.

Preparation

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 case and a calcium chloride salt in the other. The products are nearly the same. Calcium hypochlorite is manufactured by the calcium process: 2Ca(OH)2＋2Cl2→Ca(ClO)2＋CaCl2＋2H2O In another method developed for the manufacture of Ca(ClO)2, chlorine gas is reacted with calcium hydroxide: Ca(OH)2＋ 2Cl2→Ca(ClO)2＋ 2HCl In this method, it is claimed that the excess HCl is neutralized by excess Ca(OH)2 to form CaCl2. The product is said to be more “neutral” chemically and more stable than that produced by other methods.

Reactions

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.

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.

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.
