| titleOfInvention | Process for the preparation of maleimides by thermal cyclization of maleic acids |
| abstract | A process for the preparation of maleimides by thermal cyclization of maleic acids prepared by reacting maleic anhydride and a primary amine in an organic solvent consists in reacting the substituted maleic anhydride and a primary amine in an organic solvent in the presence of betanin as a catalyst at 100 to 180 ° C. substituted maleic anhydride is 0.6: 1.6 and the molar ratio between betine and primary amine is 0.01: 1.2. The maleimides obtained are purified by extraction and finally crystallized. |
