Method for recycling byproducts in synthesis of diphenyl sulfide compound

The invention provides a method for recycling byproducts in synthesis of a diphenyl sulfide compound. The byproducts comprise alkyl alcohol and dimethyl disulfide. The method comprises the steps of (1) mixing the byproducts in synthesis of the diphenyl sulfide compound with a sodium nitrite aqueous solution, adding concentrated hydrochloric acid for reaction, and obtaining alkyl nitrite and dimethyl disulfide; and (2) mixing the products obtained in the step (1) with copper powder, adding an aniline compound for reaction, carrying out desolvation treatment on the obtained reaction solution toobtain a diphenyl sulfide compound and byproducts, and returning the byproducts to the step (1). According to the recycling method, the byproducts do not need to be separated, the byproducts serve asraw materials to be directly applied to synthesis of the diphenyl sulfide compound, the process steps are simple and safe, cyclic utilization of the materials is achieved, and the raw material cost ofindustrial production of the diphenyl sulfide compound and the treatment cost of industrial three wastes are remarkably reduced.

Method for preparing 2-chloro-6-methylthio methylbenzene

The invention discloses a method for preparing 2-chloro-6-methylthio methylbenzene. The method adopts 2-chloro-6-amino methylbenzene and sodium thiomethoxide aqueous solution as raw materials, and generates 2-chloro-6-methylthio methylbenzene by diazotization. The method for preparing 2-chloro-6-methylthio methylbenzene provided by the invention overcomes the shortcomings of using 2,6-dichloro toluene as the raw material, using hexamethyl phosphoryl triamide with high polarity and high toxicity as a solvent, and using sodium thiomethoxide solid reagent which is harmful to the environment and inconvenient to use in a traditional synthesis method. Meanwhile, the method provided by the invention also solves the problem that the hexamethyl phosphoryl triamide solvent in 2-chloro-6-methylthio methylbenzene synthesized in the traditional method is difficult to recycle, and the problem of high costs and large environmental pollution and the like. The preparation method provided by the invention has the advantages of low cost, easy operation, less pollution, safety and environmental protection and the like; and the preparation method is suitable for large-scale industrialized production.

Preparation method of 2-methyl-3-chlorophenylmethyl sulfide

The present invention relates to the technical field of fluorine-containing tri-ketone pesticides and more particularly relates to a preparation method of 2-methyl-3-chlorophenylmethyl sulfide. The method comprises the following steps: 1) methyl sulfidation: 2-methyl-3-chloroaniline and methanthiol metal salts are refluxed in a solvent to synthesize 2-methyl-3-methylthio benzenamine; and 2) diazotization and chlorination: the 2-methyl-3-methylthio benzenamine is subjected to the diazotization and chlorination to synthesize the 2-methyl-3-chlorophenylmethyl sulfide. In each step of the chemical reactions, only one group of the used raw materials can conduct the reaction, so that the preparation method fundamentally avoids formation of impurities and thus improves the yield and purity of the products. The content of the prepared intermediate 2-methyl-3-chlorophenylmethyl sulfide of tembotrione is larger than or equal to 95%, the yield accounted as 2-methyl-3-methylthio benzenamine is larger than or equal to 90%, the raw materials are easy to obtain and the preparation method is easy to achieve in the industry.
