Dimepiperate

Dimepiperate is a monothiocarbamic ester and a piperidinecarboxylate ester.

g toluene or piperidine as the solvent, add α, α-dimethylbenzyl mercaptan, then add dropwise 40% sodium hydroxide solution at room temperature, reflux for reaction, and separate the water. The temperature is raised to 60-70°C, piperidinecarboxylic acid chloride is added dropwise, the precipitated sodium chloride is filtered off, the temperature is raised to react for several hours, and piperidine is obtained after washing with water, drying and desolventizing. The synthesis method of α, α-dimethylbenzyl mercaptan is as follows: 1, 4-dioxane is used as a solvent, and α-methylstyrene and hydrogen sulfide are reacted in the presence of a catalyst. The yield is 86.3%. Dimethyl sulfoxide can also be used as a solvent, the corresponding nitro compound is treated with Na2S2, and the resultant is prepared by reacting with aluminum amalgam at 0°C, with a yield of 92%.

Systemic conductivity selective herbicide in paddy field. It has outstanding effect on controlling barnyard grass before the 2nd leaf stage. The agent is absorbed by the root system, stem, and leaves and then transmitted to the entire plant, breaking the balance of endogenous auxin, thereby inhibiting intracellular protein synthesis, disrupting the division of growth point cells, and inhibiting and delaying the formation of weed stems and leaves, growth and development Stop, the stems and leaves change from thick green to yellow, brown to die. For example, after the emergence of rice dry farming, barnyardgrass 1.5-2.5 leaf stage, per 100 square meters with piperazine 50% emulsifiable concentrate 30mL plus 20% diarrhea emulsifiable concentrate 75 ~ 112.6mL, 4.5 ~ 6kg water, stem and leaf spray. Before and after sowing, dry and wet seedlings are sprayed with 50% emulsifiable concentrate 22.5-30mL per 100 square meters and sprayed with 3.75～4.5kg of water on the bed surface. The water-cultivated seedlings can be applied by poisonous soil method 1-4d after sowing . In the transplanting field, spray water with 22.5 to 39 mL of 50% emulsifiable concentrate 3 to 7 days after transplanting. After application, keep a 3 to 5 cm water layer for 5 to 7 days. When there are many types of weeds in paddy fields, they should be mixed with other herbicides.
