Preparation method of phenoxycarboxylate herbicide

The invention provides a preparation method of a phenoxycarboxylate herbicide, wherein the preparation method includes the steps: S1, carrying out condensation reaction of phenol or o-cresol with chlorocarboxylic ester under the action of alkaline substances to obtain phenoxycarboxylic ester, wherein chlorocarboxylic ester has the general formula of ClR1COOR, R1 is C1-3 alkylene or alkylidene, R is C1-10 alkyl of or C3-10 cycloalkyl; and S2, under the action of a first catalyst and a second catalyst, carrying out selective chlorination of the phenoxycarboxylic ester with a chlorinating agent to obtain the chlorophenoxycarboxylic ester represented by the formula I, R3 is H, Cl or CH3, the first catalyst is selected from Lewis acid, and the second catalyst is selected from C5-22 thioether, thiazole, isothiazole or thiophene compounds; and S3, mixing chlorophenoxycarboxylic ester with an alkaline compound, and carrying out alkaline hydrolysis to obtain the phenoxycarboxylate herbicide. The preparation method can improve the product quality and production operation environment, and has low quantity of three wastes.

Preparation method of phenoxycarboxylic acid herbicide

The invention provides a preparation method of a phenoxycarboxylic acid herbicide, wherein the preparation method includes the steps: S1, carrying out reaction of anhydrous phenol with an active metalto form phenoxide, and carrying out condensation reaction of the phenoxide with chlorocarboxylic ester to obtain phenoxycarboxylic ester, wherein the chlorocarboxylic ester has the general formula ofClR1COOR, R1 is C1-3 alkylene or alkylidene, and R is C1-10 alkyl or C3-10 of cycloalkyl; S2, carrying out selective chlorination of the phenoxycarboxylic ester with a chlorinating agent in the presence of a first catalyst and a second catalyst to obtain chlorobenzoxycarboxylic ester, wherein the first catalyst is selected from Lewis acid, and the second catalyst is C5-22 thioether, thiazole, isothiazole or thiophene compounds; and S3, carrying out acidolysis reaction of chlorobenzoxycarboxylic ester to obtain the phenoxycarboxylic acid herbicide represented by the formula I, wherein R3 is H,Cl or CH3. The preparation method can improve the product quality and the operation environment of the production site, and has low quantity of three wastes.
