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 amo
