| titleOfInvention | Preparation method of 4-p-chlorophenoxyl acetophenone compounds |
| abstract | The invention belongs to the technical field of pesticide intermediate preparation, and particularly relates to a preparation method of a 4-p-chlorophenoxy acetophenone compound. The preparation method of the 4-p-chlorophenoxy acetophenone compound comprises the following steps: (1) reacting the formula (II) with inorganic base to generate salt; (2) etherification of the obtained salt with p-dichlorobenzene to obtain the formula (III); (3) the compound shown in the formula (I) is prepared by carrying out oxidation, esterification and condensation deesterification on the obtained formula (III). After the method is adopted, the production environment is improved; and the reaction condition is relatively milder, the waste water is relatively easier to treat, and the requirements of environmental protection are met. The structural formula of the formula (I) is as follows: wherein X is chlorine, methyl or trifluoromethyl. |
