Abstract

The invention provides a production method and device for ametryn, and solves the technical problems of high energy consumption and low productivity in the production process of the ametryn. The production method comprises the following steps: dissolving the ametryn in an organic solvent to obtain an ametryn synthetic solution, and treating the ametryn synthetic solution by using a scraper evaporator to obtain an ametryn molten solution. The production device comprises the scraper evaporator; the scraper evaporator comprises a first-stage scraper evaporator, a second-stage scraper evaporator and a third-stage scraper evaporator which are connected in series. The production method device can be widely applied to the production field of s-triazine herbicide type products.

Description

technical field [0001] The invention relates to a production method and device of a herbicide, in particular to a production method and device of ametryn. Background technique [0002] At present, there are two main types of recognized production of arazine: one uses atrazine and sodium methyl mercaptide as raw materials to produce an organic solution of arazine in an organic solvent system; the other uses atrazine and sodium sulfate disulfide Methyl ester and the like are used as raw materials, and organic solvents are also used to obtain an organic solution of arazine after synthesis, such as the Chinese invention patent application whose publication number is CN101307030. [0003] The above two methods are to wash the organic phase with water and distill it, and there are disadvantages such as high energy consumption, long processing time, unstable product quality and the like in the process. Contents of the invention [0004] The purpose of the present invention is to...
