용도
개요
Carbon tetrachloride is a manufactured chemical and does not occur naturally in the environment. It is produced by chlorination of a variety of low molecular weight hydrocarbons such as carbon disulfide, methane, ethane, propane, or ethylene dichloride and also by thermal chlorination of methyl chloride. Carbon tetrachloride is a precursor for chlorofluorocarbon (CFC) gases that have been used as aerosol propellant. A decrease in this use is occurring due to the agreement reached in the Montreal Protocol for the reduction of environmental concentrations of ozone-depleting chemicals, including carbon tetrachloride.
역사
In the 1890s, commercial manufacturing processes were being investigated by the United Alkali Co. in England. At the same time it was also produced in Germany, exported to the United States, and retailed as a spotting agent under the trade name Carbona. Large-scale production of carbon tetrachloride in the United States commenced in the early 1900s. By 1914, annual production fell just short of 4500 metric tons and was used primarily for dry cleaning and for charging fire extinguishers. During World War I, U.S. production of carbon tetrachloride expanded greatly; its use was extended to grain fumigation and the rubber industry. In 1934 it was supplanted as the predominant dry-cleaning agent in the United States by perchloroethylene, which is much less toxic and more stable. During the years immediately preceding World War II, trichloroethylene began to displace carbon tetrachloride from its then extensive market in the United States as a metal degreasing solvent. Carbon tetrachloride is more difficult to recover from degreasing operations, more readily hydrolyzed, and more toxic than trichloroethylene C2HCl3. The demands of World War II stimulated production and marked the beginning of its use as the starting material for chlorofluoromethanes, by far the most important application for carbon tetrachloride.
용도
Carbon tetrachloride is used as a solvent, infire extinguishers, in dry cleaning, and in themanufacture of fluorocarbon propellents.As solvent for oils, fats, lacquers, varnishes, rubber waxes, resins; starting material in manufacture of organic Compounds. Pharmaceutic aid (solvent).
일반 설명
Carbon tetrachloride appears as a clear colorless liquid with a characteristic odor. Denser than water (13.2 lb / gal) and insoluble in water. Noncombustible. May cause illness by inhalation, skin absorption and/or ingestion. Used as a solvent, in the manufacture of other chemicals, as an agricultural fumigant, and for many other uses.
제조 및 합성 방법
생산 방법
Carbon tetrachloride is made by the reaction of carbon disulfide and chlorine in the presence of a catalyst, such as iron or antimony pentachloride: CS2 + 3Cl2 → CCl4 + S2Cl2 Sulfur chloride is removed by treatment with caustic soda solution. The product is purified by distillation. Alternatively, CCl4 may be prepared by heating a mixture of chlorine and methane at 250 to 400°C. CH4 + 4Cl2 → CCl4 + 4HCl
