| titleOfInvention | Preparation method of thermosensitive material N, N-di-N-amyl m-aminophenol |
| abstract | The invention provides a preparation method of a thermosensitive material N, N-di-N-amyl m-aminophenol, which comprises the steps of feeding, heating and dripping alkali liquor. The purity of the product prepared by the method is greatly improved, n-pentane chloride is used as a raw material, the selectivity is greatly improved, the generation of trisubstituents is avoided, side reactions are few, byproducts are few, the purity of a crude product is improved to more than 98 percent (the purity of a material layer obtained after layering) from 91 to 93 percent originally, and the purity of the product after distillation reaches more than 99.5 percent; the product prepared by the invention has the yield of 96-97 percent calculated by m-aminophenol; the invention adopts water as the solvent to replace the organic solvent in the prior art, greatly reduces the difficulty of post-treatment without influencing the reaction condition, and is more in line with the process route of green production; the invention has cheap raw materials and saves the raw material cost of 7500 yuan to 8500 yuan per ton. |
