| titleOfInvention | Preparation method of N,O-dimethyl-N-nitroisourea |
| abstract | The invention discloses a method for preparing N,O-dimethyl-N-nitroisourea by amination reaction, methylation reaction and nitration reaction. The equation is disclosed in the specification. The methyl urea obtained by the amination reaction and the monomethyl sulfate obtained by the methylation reaction can be directly used for the nitration reaction without purification. The cheap and accessible ammonia gas is used as the amination reagent in the amination reaction; in the nitration reaction, the sulfuric acid is used as a catalyst and a reaction solvent, thereby further lowering the raw material cost of the method; and the method has the advantages of mild technological conditions, wide raw material sources, lower production cost, high product quality and high content, and is easy to operate and suitable for industrial production. |
