N-nitro the amino imidazolidine referred Imidazolidine, the intermediates of the insecticide imidacloprid; used as intermediates of the efficiency and low toxicity pesticide imidacloprid
Production methods
Preparation of the cyclization of N-nitro-N-imidazolidine nitroguanidine and ethylene diamine.
Nitroguanidine and lye added in the reactor, adding ethylenediamine and 30% of industrial hydrochloric acid at 0 ° C, the suspension of the formation of salt, slowly heated to 60 ° C, the reaction 0.5h immediately transferred to pre-cooling the reactor, crystallization, centrifugal filtration, drying, get Imidazolidine.
