| titleOfInvention | A kind of method that micro passage reaction prepares nitrourea |
| abstract | The invention discloses a kind of method that micro passage reaction prepares nitrourea, belong to organic synthesis applied technical field.In the micro passage reaction that specific internal is constructed, using urea, the concentrated sulfuric acid and concentrated nitric acid as raw material, the new technology of synthesizing nitryl urea in tens seconds to reaction time a few minutes.Material is passed through after micro passage reaction by measuring pump, and nitrourea product is obtained by preheating, mixing, reaction, post processing.Beneficial effects of the present invention：Micro passage reaction technique has excellent mass-and heat-transfer effect, and safety simple to operate, product yield is high, greatly reducing the discharge capacity of spent acid. |
