| titleOfInvention | Method for producing dicarboxylic acid derivative and polybenzoxadol resin using the same |
| abstract | PROBLEM TO BE SOLVED: To provide a dicarboxylic acid derivative which is a raw material for synthesizing a chloride-free polybenzoxazole precursor and has a high purity and a high yield even in a reaction with a dicarboxylic acid other than an aromatic compound. And a method for producing the same. SOLUTION: A dicarboxylic acid and 1-hydroxy-1, When 2,3-benzotriazole is reacted in the presence of dicyclohexylcarbodiimide as a condensing agent, the temperature in the system is maintained at -5 to 20 ° C for 15 hours or more, and preferably, 1-hydroxy-1 is added to 1 mol of dicarboxylic acid. , 2,3- This is a method for producing a dicarboxylic acid derivative in which benzotriazole is reacted in a range of 2 to 2.5 mol. |
