| titleOfInvention | A kind of synthetic method of amido imide dibenzo suberol |
| abstract | A kind of synthetic method of amido imide dibenzo suberol, comprises the following steps：1）2 hydrazinoethanols, selenium dioxide and solvent orange 2 A are mixed, 2~3h is stirred in 90~110 DEG C；The solvent orange 2 A is DMSO or DMF；2）At a temperature of maintenance system, benzophenone, alkali and catalyst are added, system reacts 15~24h at 7~9 atmospheric pressure, 190~220 DEG C afterwards；In the step, the catalyst is two (tricyclohexyl phosphine) benzal chloride rutheniums；3）Post processing：After question response system cooling after be first poured into water, then to system add dichloromethane, stand filtering, filter residue successively through wash and solvent B wash after drying product；The solvent B is absolute ethyl alcohol or ether.The cost of material that the present invention uses is relatively low, is readily obtained；And process yield is higher, cost is relatively low, suitable for popularization and application. |
