| titleOfInvention | A kind of preparation technology of chlorophenol |
| abstract | The invention discloses a kind of preparation technology of chlorophenol, using phenol as raw material, using the mixture of any one in any one in any one in diphenyl sulfide and dimethyl sulphide, acetic acid and p-methyl benzenesulfonic acid, alchlor and ferric trichloride as catalyst, chlorophenol crude product is generated through chlorosulfuric acid chlorination, target product is then obtained by fusion-crystallization.The mixed catalyst that the present invention uses in the reaction has positioning action, the content of parachlorophenol in the monochlor-benzene phenol mixture of reaction generation is set to be more than 83%, make 2 in the dichloro- phenol of reaction generation, the content of 4 chlorophenesic acids is more than 98%, the three chlorinated phenol amount of impurities for generating reaction are reduced, and without purification process with regard to content can be obtained more than 99%, total recovery more than 98% 2,4,6 chlorophenesic acids, and greatly reduce the consumption of the energy, moreover it is possible to while produce the parachlorophenol of high content, with the 2 of high quality, 4 chlorophenesic acids. |
