- Design, Synthesis and Biological Activity of 2-(4-Aryloxyphenoxy) Propionamides Containing 1,3,4-Thiadiazole
-
Four new 2-(4-aryloxyphenoxy) propionamides containing 1,3,4-thiadiazole moiety were synthesized based on the structure of Quizalofop-P. The structures of the synthesized compounds were confirmed by 1H nuclear magnetic resonance, elemental analysis, and optical rotation. The herbicidal bioassay showed that the title compounds had good herbicidal activity against barnyard grass.

- Preparing method of quizalofop-p-ethyl preparation
-
The invention belongs to the field of pesticides, and provides a preparing method of a quizalofop-p-ethyl preparation. The preparing method of the quizalofop-p-ethyl preparation is characterized in that common preparing of the quizalofop-p-ethyl preparation is replaced, and a one-step method is adopted, namely, quizalofop-p-ethyl raw powder cannot be synthesized and produced, and the quizalofop-p-ethyl preparation can be directly produced and prepared. The preparing method of the quizalofop-p-ethyl preparation, provided by the invention, has the maximum advantages that resource integration is realized, crystallizing and drying steps are removed, the labor amount is reduced, the yield is increased, the production cost is reduced, and mother liquor-black oil is prevented from being generated. The preparing method can be used for preparing the following preparations: 5 to 25 percent of quizalofop-p-ethyl EC (Emulsifiable Concentrate), 5 to 15 percent of quizalofop-p-ethyl microemulsion, 5 to 10 percent of quizalofop-p-ethyl EW (Emulsion in Water), 5 to 50 percent of quizalofop-p-ethyl dry suspension concentrate, 5 to 20 percent of quizalofop-p-ethyl water suspension concentrate, quizalofop-p-ethyl oil suspension concentrate, quizalofop-p-ethyl composite EC, composite microemulsion, composite EW, composite dry suspension concentrate, composite water suspension concentrate and composite oil suspension concentrate.
