Preparation method of 2,4-dichlorophenoxyacetic acid and salt thereof

The invention provides a preparation method of 2,4-dichlorophenoxyacetic acid and a salt thereof, wherein the preparation method includes the following steps: S1) carrying out a reaction of phenol andchloracetic ester under alkaline conditions to obtain phenoxyacetic ester; S2) carrying out selective chlorination reaction of the phenoxyacetic ester with a chlorinating agent under the action of acatalyst A and a catalyst B to obtain 2,4-dichlorophenoxyacetic ester, wherein the catalyst A is Lewis acid, and the catalyst B is C5-22 thioethers, thiazoles, isothiazoles and thiophenes or halogenated derivatives thereof; and S3) carrying out hydrolysis reaction of 2,4-dichlorophenoxyacetic ester under acidic conditions to obtain 2,4-dichlorophenoxyacetic acid; or after 2,4-dichlorophenoxyaceticester is obtained, carrying out an alkaline hydrolysis reaction with an alkaline compound to obtain 2,4-dichlorophenoxyacetate. The production and use of 2,4-dichlorophenol with unpleasant odor are avoided, the production of dioxins is eliminated, the yield of products is improved, and the output of three wastes is greatly reduced.

Preparation method of 2,4-dichlorophenoxyacetic ester

The invention provides a preparation method of 2,4-dichlorophenoxyacetic ester, wherein the preparation method includes the following steps: S1) carrying out a reaction of phenol and methyl chloroacetate under alkaline conditions to obtain methyl phenoxyacetate; S2) carrying out selective chlorination reaction of methyl phenoxyacetate with a chlorinating agent under the action of a catalyst A anda catalyst B to obtain 2,4-methyl dichlorophenoxyacetate, wherein the catalyst A is Lewis acid, and the catalyst B is C5-22 thioethers, thiazoles, isothiazoles and thiophenes or halogenated derivatives thereof; and S3) carrying out transesterification reaction of 2,4-methyl dichlorophenoxyacetate and alcohol under the action of a catalyst, to obtain 2,4-dichlorophenoxyacetic ester, wherein the alcohol is C2-20 alcohol. The selective chlorination reaction is carried out with methyl phenoxyacetate as a raw material, the selectivity of the reaction is improved, the loss of effective components isavoided, the yield of the effective components is greatly improved, and the three-waste treatment capacity, the three-waste treatment difficulty and the treatment cost are reduced.
