Synthesis method of 2-(2,4,6-trichlorophenoxy)ethyl propylamine

The invention discloses a synthesis method of 2-(2,4,6-trichlorophenoxy)ethyl propylamine. The method comprises the following steps: reacting 2,4,6-trichlorophenol with cycloethylamine under the catalysis of boron trifluoride diethyl ether, and conducting salifying with hydrochloric acid to obtain a compound A; and under the catalysis of cesium hydroxide monohydrate, reacting the compound A with 1-bromopropane by taking sodium carbonate as an acid-binding agent to obtain 2-(2,4,6-trichlorophenoxy)ethyl propylamine. The method is simple in operation steps, the used reaction raw materials are cheap and easy to obtain, total molar yield is 94.18%, the purity of the produced 2-(2,4,6-trichlorophenoxy)ethyl propylamine is 98.0% or above, product quality is good, and the method is suitable for industrial production.

Safe and reliable prochloraz preparation method

The invention discloses a safe and reliable prochloraz preparation method. The safe and reliable prochloraz preparation method comprises following steps: S1, etherification reaction, wherein 2, 4, 6-trichlorophenol, a liquid alkali, and dichloroethane are subjected to sealing heating reaction so as o obtain a S1 etherification intermediate; S2, amination reaction, wherein propylanmine is added, heating reaction is carried out, distillation recycling of propylanmine is carried out, and extraction is carried out so as to obtain a S2 secondary amine intermediate solution; S3, esterification reaction, wherein an acid binding agent A, and a halogenated formate are added, room temperature reaction is carried out for 1 to 3h, and filtering is carried out so as to obtain a S3 esterification intermediate solution; and S4, carbonylation condensation reaction, wherein catalyst B and imidazole are added, reflux reaction is carried out, and washing, extraction, and distillation are carried out so as to obtain prochloraz finished product. According to the safe and reliable prochloraz preparation method, the halogenated formate is adopted to replace a phosgene similar agent as a carbonylation condensation reagent, and sealing, waterless, and rectification reflux reaction conditions are adopted, so that continuous production is realized; the prochloraz total yield is high; no phosgene leakagesafety hidden trouble is caused; and the safe and reliable prochloraz preparation method is worthy of popularization.
