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 method for preparing Clothianidin, the specific step includes: using 1, 5 – dimethyl – 2 – nitro imine hexahydro – 1, 3, 5 – triazine, 2 – chloro – 5 chloro methyl thiazole, potassium carbonate is dissolved in the N – N – dimethyl formamide, reaction, after-treatment, cooling, filtering, drying to obtain 1 – (2 – chloro – 5 – thiazolyl) – methyl – 3, 5 – dimethyl – 2 – nitro imine – hexahydrotriazine solid, re-dissolved in toluene, adding concentrated hydrochloric acid, the temperature of the reflux 10h, urea neutralization, is divided into several layers, washing, desolution get clothianidine solid. The catalyst of the invention is little consumption, high recovery rate; can make the conversion rate of Clothianidin ? 86.3%; solvent toluene can be recycled; Clothianidin preparation of high purity of the product, there is little impurity content, molar yield high, has made good economic benefits; preparation method safety, environmental protection, and is applicable to industrial production, and has a wide application.
