| titleOfInvention | A kind of synthetic method of 2,6-di-isopropyl-4-phenoxybenzamine |
| abstract | The present invention relates to a kind of synthetic method of 2,6-di-isopropyl-4-phenoxybenzamine.The method is raw material with 2,6-DIPA, is dissolved in solvent, adds sulfuric acid and drip nitric acid, and reaction generation 2,6-di-isopropyl-4-N-methyl-p-nitroaniline, directly carries out lower step condensation reaction without separation, obtain 2,6-di-isopropyl-4-phenoxybenzamine.Adopt quaternary ammonium salt to make catalyzer, temperature of reaction is down to 110 DEG C by 140 DEG C, reduces the requirement to conversion unit, shortens the technical process cycle.The present invention is simple to operate, environmental protection, cost are low, and product selectivity is high, yield is high, purity is high, is more suitable for scale suitability for industrialized production. |
