티오페놀 C화학적 특성, 용도, 생산
개요
분자량110.2, 녹는점-14.8℃, 끓는점168.7℃, 비중1.078(측정온도 14℃), 굴절률=1.5893이다.무색의 액체로 메르캅탄 특유의 악취가 있다.
용도
공기 속에서 산화되면 디페닐디술피드(CHSSCH)를 생성하며, 수소를 내보내고 이황화페닐(CHS)이 되기 쉬우므로 환원제로도 사용된다.
화학적 성질
colorless liquid
출처
Reported found in cooked/boiled beef.
용도
Thiophenol is used as a mosquito larvicideand as an intermediate in organic synthesis.It is effective in reducing peroxide formationin jet fuels (Watkins et al. 1989).
제조 방법
By reduction of benzenesulfonyl chloride with zinc dust in sulfuric acid.
정의
ChEBI: A thiol in which the sulfanyl group is attached to a phenyl group.
일반 설명
A clear liquid with a repulsive odor. Boiling point 168.3°C. Insoluble in water and denser than water. Very toxic by ingestion, skin absorption, and by inhalation. Used as a chemical intermediate and in mosquito control.
공기와 물의 반응
Flammable. Oxidizes upon exposure to air, especially when dissolved in alcoholic ammonia, to form diphenyl disulfide, C6H5SSC6H5 [Merck 11th ed. 1989]. Is supplied under an atmosphere of nitrogen. Insoluble in water.
반응 프로필
Thiophenol reacts with acids to generate toxic fumes of oxides of sulfur. [Lewis, 3rd ed., 1993, p. 1021]. Reacts exothermically with strong oxidizing agents.
위험도
Skin irritant.
건강위험
Animal toxicity data show thiophenol to behighly toxic; the oral LD50 value in testanimals is <100 mg/kg. Its irritant actionon rabbits’ eyes and skin is severe. Thiophenol can enter the body by ingestion,absorption of the liquid through the skin,and inhalation of vapors. In humans, thetoxic symptoms include restlessness, incoordination, muscle weakness, headache, dizziness, cyanosis, lethargy, sedation, respiratorydepression, and coma. Death may result fromhigh doses. Repeated exposure to thiophenol vapors caused injury to the lung, liver,and kidneys in mice. Thiophenol did notadversely affect the growth, viability or morphological development of the offspring at adose of 40 mg/kg/day in rabbits (NTP 2005).LC50 value, inhalation (mice): 28 ppm/4 hLD50 value, oral (rats): 46 mg/kgLD50 value, skin (rats): 300 mg/kg.
화재위험
When heated to decomposition or on contact with acids, Thiophenol emits toxic fumes of sulfur oxides. May be ignited by heat, sparks or flames. Container may explode in heat of fire. Vapor explosion and poison hazard indoors, outdoors or in sewers. Unstable, oxidizes in air. Avoid contact with acids.
Safety Profile
Poison by ingestion, inhalation, skin contact, and intraperitoneal routes. A severe eye irritant. Can cause severe dermatitis. Exposure may cause headache and dminess. When heated to decomposition or on contact with acids it emits toxic fumes of SOx. See also MERCAPTANS
잠재적 노출
Phenyl mercaptan is used as a chemical intermediate in pesticide manufacture; as a mosquito larvicide. It is used in solvent formulations for the removal of polysulfide sealants.
운송 방법
UN2337 Phenyl mercaptan, Hazard class: 6.1; Labels: 6.1-Poisonous materials, 3-Flammable liquid, Inhalation zone B.
비 호환성
At normal room temperature may vaporize forming explosive mixture with air. Violent reaction with strong oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, calcium hypochlorite, alkali metals. Oxidizes on exposure to air; supplied under nitrogen.
