n-도데실메르캅탄 C화학적 특성, 용도, 생산
화학적 성질
1-Dodecanethiol is a colourless liquid organic compound, with a characteristic odour. Soluble in methanol, ether, acetone, benzene, ethyl acetate, insoluble in water.용도
1-Dodecanethiol is used in the preparation of hydrophobic or mixed self-assembled monolayers. It is also employed as a chain transfer agent for radical polymerization. Further, it is utilized as a polymerization inhibitor in polyurethane and neoprene adhesives, which finds application in the footwear industry. In addition to this, it acts as a protein regenerating agent used for the regeneration of native proteins from mercuribenzoate.제조 방법
Preparation of 1-dodecanethiol: 1-Bromododecane, thiourea and 95% ethanol are heated to reflux reaction, then sodium hydroxide solution is added and heated. After the reaction is finished, cooled and left to stratify, the oil layer is the crude thiol. The crude product is washed with water, dried, distilled, and distilled under reduced pressure, which is 1-dodecanethiol.일반 설명
Oily colorless liquid with a mild skunk odor. Freezing point 19°F.공기와 물의 반응
Air and moisture sensitive. Insoluble in water. Reacts vigorously with water or steam.반응 프로필
1-Dodecanethiol is incompatible with bases, oxidizing agents, reducing agents and alkali metals. Easily oxidized to disulfide.건강위험
1-Dodecanethiol is irritating to skin, eyes, and mucous membranes. Ingestion may cause nausea. Repeated skin exposure can cause dermatitis and may produce a sensitizing effect. It is very toxic to aquatic life with long lasting effects.화재위험
Special Hazards of Combustion Products: Poisonous and irritating gases (e.g., sulfur dioxide) are generated in fires.Purification Methods
Dry it with CaO for several days, then distil it from CaO. [Beilstein 1 IV 1851.]n-도데실메르캅탄 준비 용품 및 원자재
