| titleOfInvention | Thiourea is as the application of solid nitration reagent |
| abstract | The invention discloses the application of thiourea as solid nitration reagent, add thiocarbamide and water in a kettle., under stirring, heat naturally cooling; When crystal starts to separate out, drip mass concentration is concentrated nitric acid, and nitric acid dropping is complete, and cooling suction filtration, obtains solid nitric acid thiocarbamide.Its technique is simple, and product purity is higher, and yield is better, is a kind of green synthesis method of applicable suitability for industrialized production solid nitration reagent thiourea.Solid nitric acid thiocarbamide is as the application of nitrating agent.Solid nitric acid thiocarbamide prepared by the present invention is applied to the nitrated of aromatic compounds as nitrating agent, and when carrying out nitration reaction, reaction conditions is gentle, and side reaction is relatively less; And solid nitration reagent is easy to store and transport. |
