| titleOfInvention | The preparation method of salicylonitrile and its derivative |
| abstract | The invention belongs to organic chemical industry field, is related to a kind of preparation method of salicylonitrile and its derivative.Using Acket as raw material, using organic phosphorus compound as catalyst, using aromatic solvents and/or halogenated hydrocarbons as solvent, add phosgene reaction and obtain salicylonitrile, add alkali reaction and can obtain salicylonitrile derivative.The method that the present invention prepares salicylonitrile and its derivative, cost is low, high as catalyst, catalytic activity present invention uses organic phosphorus compound, it can be recycled, reaction is abundant, and impurity is few, and the relative response time shortens, product yield is up to more than 98% (in terms of Acket), product content is and easy to operate, efficient and environmentally friendly up to more than 98%, is conducive to large-scale industrial production. |
