Abstract

The invention provides a synthetic process of an acaricide, relating to a synthetic process of an insecticide. More specifically, the invention relates to a synthetic process of an acaricide. The invention provides the synthetic process of the acaricide which is high in purity and yield. The invention adopts the following technical scheme: the process comprises the process steps of: synthesizing 2-(4-tertbutyl-phenoxy) cyclohexanol; synthesizing 2-(4-tertbutyl-phenoxy) cyclohexyl chloride sulfite; and synthesizing a propargite original medicine.

Description

Technical field: [0001] The present invention relates to a kind of synthetic technique of insecticide, more specifically, relate to a kind of synthetic technique of acaricide. Background technique: [0002] Acetate, also known as propargate, is a highly efficient and low-toxic acaricide, which has a good control effect on fruit trees, cotton, vegetables, and a wide range of phytophagous mites. At present, most domestic manufacturers use p-tert-butylphenol to react with epoxycyclohexane under alkali catalysis (110~130℃), and then remove excess epoxycyclohexane to obtain 2-(4-tert-butyl Phenoxy) cyclohexanol, the content is more than 95%; then react with thionyl chloride, and then remove excess thionyl chloride to obtain 2-(4-tert-butylphenoxy)cyclohexyl chloride Sulfuric acid ester; finally react with propynyl alcohol in an environment with excess acid-binding agent (triethylamine or pyridine), and then remove the solvent in the system to obtain the crude oil of diclofenac. ...
