| titleOfInvention | The synthetic method of 2- nitropropane |
| abstract | The invention discloses a kind of preparations for replacing saturated hydrocarbons, more particularly to a kind of synthetic method of 2- nitropropane, it is aoxidized by different hydrazone and is obtained, include the following steps: that S1, acetone, water and ammonia are condensed in the presence of a catalyst and generates ketimide, wherein the mass ratio of acetone and water is 1:(1~5), catalyst amount is the 5-11% of acetone dosage；S2, the ketimide of step S1 is taken to aoxidize the different hydrazone of generation, temperature of reaction system is 30-60 DEG C, and the insulation reaction time is 0.5-3h；S3, the different hydrazone of step S2 is taken to aoxidize generation 2- nitropropane, temperature of reaction system is 50-80 DEG C, soaking time 0.5-3h；Gained initial action liquid is rectifying to obtain qualified 2- nitropropane product.The invention has the advantages that catalytic oxidation mild condition, technical process are simple and convenient to operate using acetone, ammonia, water as starting material, not cogeneration of propanone oxime or ketazine, it is suitble to produce 2- nitropropane in enormous quantities, and post-processes easy, product purity height. |
