| Use | propanethiol is N-propanethiol, also known as thiopropanol, 1-mercaptopropane, in the production of pesticides can be used for the synthesis of organophosphorus insecticides propylsulfur phosphorus, sulfur phosphorus, nematicide and soil insecticide insecticide phosphorus, herbicide grams grass enemy intermediates, also used as intermediates in other organic synthesis. used as intermediates in pesticides and other organic synthesis. it can be used as raw materials for organic synthesis, and is also an intermediate of pesticide and insecticide. 1-propanethiol is used as an organic synthesis reactant for several organic compounds, including organic synthesis reactants rich in leucine repeat kinase 2(LRRK2) inhibitors, which have potential for the treatment of Parkinson's disease. It is also used as a component of certain herbicides. |
| production method | 1. Obtained by the reaction of bromopropane with thiourea. The methanol solution of thiourea and bromopropane was refluxed for 3H. After methanol was recovered, dilute sodium hydroxide solution was added and refluxed for 6H. Then, dilute sulfuric acid was slowly added dropwise, and propanethiol was distilled at any time. After the addition of dilute sulfuric acid was completed, the distillation was continued until no oil beads were distilled. The collected oil layer was crude, dried with anhydrous calcium chloride, and then distilled, and the fraction with boiling point of 66.5-76.5 ° C. Was collected as the finished product. 2. By the role of halogenated propane and sodium hydrosulfide derived. 3. Propyl mercaptan can also be obtained by catalytic reaction of propyl alcohol with hydrogen sulfide at 300-380 °c. The preparation method is derived from the reaction of bromopropane with thiourea. Thiourea and bromopropane were refluxed in methanol solution for 3H. After methanol was recovered, dilute sodium hydroxide solution was added and refluxed for 6H. Then, dilute sulfuric acid was slowly added dropwise, followed by distillation of propanethiol. After the addition of dilute sulfuric acid was completed, the distillation was continued until no oil beads were distilled. The collected oil layer was a crude product, dried with anhydrous calcium chloride, and then subjected to rectification, and the B. p.66.5 ~ 76.5 ° C. Fraction was collected as the finished product. In addition, propanethiol can also be obtained by catalytic reaction of propanol and hydrogen sulfide at 300 to 380 °c. |
