Physical and Chemical Properties | Imidazolidine pure white crystals, m.p.213 ~ 215 ℃ (decomposition), industrial products for white or light yellow powder, content is greater than or equal to 98.0%, slightly soluble in cold water, soluble in hot water. |
Use | Used as a high efficiency and low toxicity pesticide imidacloprid intermediates; Used as pesticide intermediates, mainly for the synthesis of a net pesticide |
Uses | N-nitroimidazolidine is abbreviated as imidazolidine, which is an intermediate of the insecticide imidacloprid. Used as an intermediate for high-efficiency and low-toxicity pesticide imidacloprid |
Production method | The preparation method is to cyclize nitroguanidine and ethylenediamine to obtain N-nitroimidazolidine. Nitroguanidine and lye are added to the reaction kettle, ethylenediamine and 30% industrial hydrochloric acid are added at 0 ℃ to form a salt suspension, slowly raise the temperature to 60 ℃, react for 0.5h, and immediately transfer to the precooling kettle. Imidazolidine is obtained by crystallization, centrifugal filtration and drying. |
