| titleOfInvention | Method for producing dicarboxylic acid derivative, alkali-soluble heat-resistant resin precursor and photosensitive heat-resistant resin precursor composition using the same |
| abstract | To provide a production method capable of obtaining a high purity dicarboxylic acid derivative by a simple method. A compound represented by the following general formula (1) dissolved in a basic aqueous solution and a compound represented by the following general formula (2) dissolved in an organic solvent that does not substantially dissolve in the basic aqueous solution. A method for producing a dicarboxylic acid derivative represented by the following general formula (3), wherein an interfacial reaction is performed. R 1 -AH (1) X-CO-R 2 -CO- X (2) R 1 —ACO—R 2 —COA—R 1 (3) (In the above formula, R 1 represents a nitrogen or sulfur atom-containing group having 1 to 20 carbon atoms, R 2 represents a divalent group having 2 to 30 carbon atoms, A represents an oxygen atom or a sulfur atom, and X represents It may be the same or different and represents a chlorine atom, a bromine atom or an iodine atom.)
