| titleOfInvention | Method for producing bis-imide dicarboxylic acid |
| abstract | It is an object of the present invention to provide a process for producing an industrially advantageous bis-imine dicarboxylic acid which does not substantially use a solvent and which does not need to be granulated after completion of the reaction.nThe object is achieved by a method for producing a bis-imine dicarboxylic acid, which is a method for producing a bis-imide dicarboxylic acid from a tricarboxylic anhydride and a diamine, and comprises the following steps (i), (ii) Step (i): when a component having a higher melting point among a tricarboxylic anhydride or a diamine is a high melting point component, and a component having a lower melting point is a low melting component, the melting point of the component which does not reach the high melting point is low. a step of obtaining a mixture by heating a high melting point component above the melting point of the melting point component, and adding a low melting point component to the high melting point component in such a manner that the high melting point component is maintained in a solid state; and the step (ii): in the step (i) The mixture obtained in the above is heated in such a manner as to maintain its solid state to obtain a bis-imide dicarboxylic acid. |
