|Section2= |Section3= }} 1,1,2,2-Tetrachloroethane is a chlorinated derivative of ethane. It has the highest solvent power of any chlorinated hydrocarbon.〔 As a refrigerant, it is used under the name R-130. It was once widely used as a solvent and as an intermediate in the industrial production of trichloroethylene, tetrachloroethylene, and 1,2-dichloroethylene.〔Agency for Toxic Substances and Disease Registry (ATSDR). Toxicological Profile for 1,1,2,2-Tetrachloroethane (Update). U.S. Public Health Service, U.S. Department of Health and Human Services, Atlanta, GA. 1996.〕 However, 1,1,2,2-tetrachloroethane is no longer used much in the United States due to concerns about its toxicity.〔(Tetrachloroethane ) at U.S. EPA〕 Chronic inhalation exposure in humans results in jaundice and an enlarged liver, headaches, tremors, dizziness, numbness, and drowsiness. The U.S. Environmental Protection Agency has classified it as a Group C possible human carcinogen.〔 For occupational exposure limits, the Occupational Safety and Health Administration has set a permissible exposure limit for dermal exposures at 5 ppm over an eight-hour time-weighted average. The National Institute for Occupational Safety and Health has a more protective recommended exposure limit for dermal exposures at 1 ppm over an eight-hour time-weighted average.〔(CDC - NIOSH Pocket Guide to Chemical Hazards )〕 == See also== * 1,1,1,2-Tetrachloroethane 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「1,1,2,2-Tetrachloroethane」の詳細全文を読む スポンサード リンク
