| titleOfInvention | A kind of synthesis technique of N-methyl-N ' nitroguanidine |
| abstract | The invention belongs to the synthesis technique of a kind of N-methyl-N ' nitroguanidine of pesticide intermediate technical field, this technique comprises following production stage: (1) drops into nitrosonitric acid and the vitriol oil in reaction flask, and adds S-methyl-isourea under agitation; (2) after reaction terminates, on the rocks, suction filtration, does vacuum-drying, obtain N-? nitromethyla thiocarbamide powder; (3) first drop into methyl alcohol in reaction flask, add dry N-nitromethyla thiocarbamide, under room temperature, drip methylamine alcohol solution; (4) then at 80 DEG C, react 3h, filtered while hot, cooling, suction filtration, filter cake vacuum-drying, obtains N-methyl-N ' nitroguanidine solid.This technique is optimized reaction conditions, has saved cost, makes overall yield bring up to 85%. |
