| titleOfInvention | Method for producing aliphatic maleimide |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing aliphatic maleimide which can be efficiently obtained with high selectivity and high yield by suppressing generation of by-products by simple operation under mild conditions and simple operation. provide. A method for producing an aliphatic maleimide represented by the following general formula (2): Heating and refluxing to a solution containing maleic anhydride, an acid catalyst, a tertiary amine of 0.15 to 0.8 molar equivalents with respect to the acid catalyst as a dehydration cocatalyst, and an organic solvent capable of azeotroping with water Below, the manufacturing method of the aliphatic maleimide which supplies an aliphatic primary amine or its solution represented with following General formula (1), and carries out a cyclodehydration cyclization in a homogeneous reaction system. R represents an n-valent aliphatic hydrocarbon group, and n is an integer of 1 to 6. 【Selection chart】 None |
