Abstract

By the method of experimental research combined with reference to relevant documents, the study initially synthesized and purified pralidoxime chloride through 3 stages of pyridine 2-aldoxime synthesis, pralidoxim methylsulfate and pralidoxim chloride from the primary materials 2-formyl pyridine, hydroxylamin hydrochloride, dimethylsulfate and hydrochloric acid. The study results showed that the efficiency of the reaction of the synthesis of pyridine 2-aldoxime, pralidoxim methylsulfate and pralidoxim chloride, respectively, was 55.2% -73.4%; 84.9% and 86.4%. The purification process is determined by the ratio of crude product and solvent is 1 g / 1 ml water / 10 ml isopropanol. The final synthetic product was structured and confirmed to be pralidoxime chloride based on melting point, IR spectrum, MS spectrum and NMR spectrum. This is the basis for the synthesis of pralidoxime as a raw material for the preparation of emergency injections neurotoxicicity.
