Quinmerac and preparation method thereof
The invention relates to the field of herbicide synthesis, particularly to quinmerac and a preparation method thereof. The method includes the steps: in the presence of a catalyst, carrying out an oxidation reaction on 3,8-dimethyl-7-chloroquine as a raw material, carboxylic acid as a solvent and oxygen-containing gas as an oxidizing agent, wherein the catalyst is one or more of a cobalt metal compound, a manganese metal compound and a vanadium metal compound. According to the method, a large amount of waste acid and waste water can be prevented from being generated, environmental protection is achieved, and the three-waste treatment cost is greatly reduced; and the method has the advantages of mild reaction conditions, simple post-treatment and high product purity and yield, and is very suitable for industrial production.
