A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 105827-91-6, Name is 2-Chloro-5-(chloromethyl)thiazole, molecular formula is C4H3Cl2NS. In a Patent£¬once mentioned of 105827-91-6, Quality Control of: 2-Chloro-5-(chloromethyl)thiazole
The invention discloses a 2 – chloro – 5 – chloromethyl-thiazole of the preparation method, comprises the following steps: S1, will be 1 – isothiocyanate yl – 2 – chloro – 2 – propylene adding organic solvent, at a temperature of 5 C -20 C to proceed chlorination reaction; S2, recycling the organic solvent, the gas hydrogen chloride derived; S3, organic solvent recovery after the completion of the, heating up and through the distilled under reduced pressure to get the pure product 2 – chloro – 5 – chloromethyl-thiazole. According to the embodiment of the invention of 2 – chloro – 5 – chloromethyl-thiazole of the preparation method using a large amount of hydrochloric acid in the refining process, has simplified the reaction step, mild reaction conditions, there is no three waste, high yield, in line with the direction of development of green chemistry.
