-
Paragraph 0069-0073, (2021/06/22)
The invention provides a preparation method of a benzoyl chloride compound. The preparation method comprises the following step: with a trichloromethyl benzene compound and a benzoic acid compound as raw materials and ferric oxide as a catalyst, carrying out a catalytic reaction to prepare the benzoyl chloride compound. According to the method disclosed by the invention, the benzoyl chloride compound can be obtained under the condition of not using a solvent, yield is up to 95% or above, atom economy is good, cost is lower, operation is simpler, more convenient and safer, the treatment amount of three wastes is smaller, the three wastes is easier to treat, and the method is more suitable for industrial production.
