| titleOfInvention | Synthesis method of triphenylchloromethane |
| abstract | The invention discloses a synthesis method of triphenylchloromethane, which relates to the technical field of medical intermediates and comprises the following steps of S1, mixing and stirring benzene and anhydrous ferric trichloride for 10-15min, and dripping carbon tetrachloride when the liquid temperature is lower than 15 ℃; s2, after the dropwise addition is finished, heating to 150 ℃ while stirring, keeping the kettle pressure at 0.6-0.65MPa, and carrying out heat preservation and pressure maintaining reaction for 1 h; s3, carrying out post-treatment on the reaction liquid obtained in the step S2 to obtain the triphenylchloromethane. The synthesis method of the triphenylchloromethane takes anhydrous ferric chloride as a catalyst, the mass ratio of the carbon tetrachloride to the ferric chloride is 1:0.01-0.5, the occurrence of side reactions is reduced, the post-reaction treatment is simplified, the generation amount of waste water is reduced, the reaction yield reaches 80-82%, and the purity reaches more than 99%. |
