Dodecane-1-thiol 112-55-0

  ses: n-Dodecanethiol can be used as a relative molecular mass regulator for polymer compounds. Preparation: Heat bromododecane, thiourea, and 95% ethanol to reflux, then add sodium hydroxide solution and heat. After the reaction is complete, cool and allow to separate into layers. The oily layer is crude mercaptan. The crude product is washed with water, dried, distilled, and then distilled under reduced pressure to obtain n-dodecyl mercaptan. Safety: Vapor or mist is irritating to the nose and throat. Vapor or mist of this product is irritating to the nose and throat. Inhalation of high concentrations can cause headaches, nausea, vomiting, and even coma. It is hazardous to the environment, and attention should be paid to pollution to the water environment and aquifers. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Avoid direct sunlight. Keep the container sealed. Store separately from oxidants, acids, and edible chemical raw materials. Chemical Properties: Colorless or pale yellow liquid. Melting point -7°C, boiling point 165-169°C (5.19kPa), 142-145°C (2kPa), relative density 0.8450 (20/20°C), refractive index 1.4589, flash point 87°C. Soluble in methanol, ether, acetone, benzene, ethyl acetate, insoluble in water.
