Preparation method for utilizing nitration method to synthesize pendimethalin
The invention discloses a pendimethalin preparation method, especially relates to a preparation method for utilizing a nitration method to synthesize pendimethalin and belongs to the field of medicinepreparation. According to a preparation principle, a technical route of utilizing amidation at first to protect amino, then performing nitration and then performing acidolysis is utilized. The methodcomprises the steps: utilizing N-(1-ethyl propyl)-3,4-dimethylaniline as a beginning raw material, utilizing dichloroethane as a solvent, performing amidation with acetic anhydride, then nitrifying through concentrated nitric acid and then performing acidolysis to prepare pendimethalin under the dilute sulphuric acid action. The herbicide pendimethalin synthesizing method has the advantages of high yield and purity, greenness and environmental friendliness. Compared with the prior art, the preparation method has a stable and reliable technology and achieves more greenness and environmental friendliness.

Safe, efficient and selective synthesis of dinitro herbicides via a multifunctional continuous-flow microreactor: One-step dinitration with nitric acid as agent
A continuous and selective method for synthesis of dinitro herbicides through one-step dinitration approach has been successfully developed in microreactor systems. Compared to a conventional two-step batch process, reaction can be conducted without the need to separate intermediates and much less solvent or solvent-free condition has been employed.
