Method for production of N-phenyl and N-cyclohexyl maleimides |
| abstract |
A method for the production of maleimides, which comprises subjecting maleinamic acids to ring-closure imidation in an organic solvent capable of forming an azeotrope with water in the presence of an acid catalyst at a temperature in the range of 120 DEG C. to 250 DEG C. while removing the formed water in the form of an azeotrope with said organic solvent and thereafter purifying the produced maleimides. |
