摘要： An object of the present invention is to provide an industrially advantageous method for producing a bisimide dicarboxylic acid, which uses substantially no solvent and requires no granulation after completion of the reaction.
The above object can be achieved by a method for producing a bisimide dicarboxylic acid with a tricarboxylic acid anhydride and a diamine, including the following processes (i) and (ii):
a process (i) in which, provided that a compound having a higher melting point is a high melting compound and a compound having a lower melting point is a low melting compound, when a melting point is compared between the tricarboxylic acid anhydride and the diamine, the high melting compound is heated at a temperature between less than the melting point of the high melting compound and not lower than the melting point of the low melting compound, and the low melting compound is added to the high melting compound while the high melting compound maintains its solid states, to give a mixture; and
a process (ii) in which the resultant mixture in the process (i) is heated while its solid states are kept, to give bisimide dicarboxylic acid.
