Paragraph 0018; 0020; 0023; 0025; 0028-0032; 0033; 0035, (2019/01/08)
The invention discloses a synthetic method for an alkylpolyamine bactericide Xinjunan, belonging to the technical field of pesticides. According to a technical scheme of the invention, the synthetic method comprises the following steps: heating a diethylenetriamine solution containing water and an acid-binding agent to 100 to 140 DEG C, dropwise adding 1-chlorooctane under stirring and a heat-preserving condition within 2 to 2.5 hour, carrying out standing for 5 hours with a temperature maintained at 190 to 210 DEG C after completion of the addition of 1-chlorooctane, carrying out layering, and performing vacuum extraction to obtain a supernatant liquid 1 for subsequent usage; and adding water into remaining subnatant solid, carrying out heating to 90 DEG C, carrying out standing for layering, and combining an obtained supernatant liquid 2 with the supernatant liquid 1 so as to obtain a Xinjunan mother liquor. The synthetic method provided by the invention has the following beneficialeffects: the addition amount of the diethylenetriamine is reduced, so the loss of the diethylenetriamine is decreased; meanwhile, distillation recovery of the diethylenetriamineis not needed, so raw material and power cost is reduced; compared with the prior art, the synthetic method provided by the invention can reduce the cost by about 8,000 yuan per ton, and is more environmentally-friendly inthe whole synthetic reaction and post-treatment process; and the Xinjunan prepared by using the synthetic method provided by the invention has higher effective content.

Paragraph 0017; 0019, (2017/01/26)
The invention discloses a preparation method of N1-n-octyl-N2-[2-(n-octylamino) ethyl]-1,2-ethidene diamine. The method comprises the following steps: by using diethylenetriamine and 1-n-octanal as raw materials, carrying out condensation in the presence of a catalyst to generate N1-n-octyl amine-N2-[2-(n-octyl amine) ethyl]-1, 2-ethidene diamine; further hydrogenating N1-n-octyl amine-N2-[2-(n-octyl amine) ethyl]-1, 2-ethidene diamine to obtain N1-n-octyl-N2-[2-(n-octylamino) ethyl]-1, 2-ethidene diamine. The preparation method disclosed by the invention is used for solving the problem that the product prepared from N1-n-octyl-N2-[2-(n-octylamino) ethyl]-1, 2-ethidene diamine raw medicines in the prior art is low in content and yield and more in byproducts and the post treatment is complex. The preparation method disclosed by the invention is mainly used for preparing N1-n-octyl amine-N2-[2-(n-octylamino) ethyl]-1, 2-ethidene diamine. The obtained product can be used for bactericides in oil fields, farms and papermaking. The structure of N1-n-octyl amine-N2-[2-(n-octylamino) ethyl]-1,2-ethidene diamine is shown in the specification.
