| titleOfInvention | Preparation method of p-chlorothiophenol |
| abstract | The invention relates to a simple preparation method of p-chlorothiophenol, which comprises the steps of taking sodium p-chlorobenzenesulfonate and thionyl chloride as raw materials, taking methylbenzene as a solvent, reacting for 3-5 hours at 50-70 ℃ under the action of a phase transfer catalyst to prepare p-chlorobenzenesulfonyl chloride, controlling the temperature at 40-60 ℃ under an acidic condition, and reducing by using iron powder to obtain the p-chlorothiophenol. The method has the characteristics of low cost, simple and convenient operation and suitability for industrial production. |
