Preparation method for 4-phenylthio-benzenethiol |
| abstract |
The present disclosure discloses a preparation method for 4-phenylthio-benzenethiol. The preparation method comprises the following steps: subjecting phenyl sulfide as a raw material to a halogenation reaction to obtain 4-halophenyl sulfide; subjecting the 4-halophenyl sulfide to a sulfhydrylation reaction to obtain a 4-phenylthio-phenylthiolate; and subjecting the 4-phenylthio-phenylthiolate to acidification. The preparation method of the present disclosure avoids the use of materials such as thiophenol which pollutes the environment, and realizes efficient recycling of the reaction materials, solvents, water and the like. The preparation method of the present disclosure is a green process for the synthesis of 4-phenylthio-phenylthiol without organic waste, waste acid and waste water discharge. |
