Method for producing tetracarboxylic acid and acid dianhydride |
| abstract |
[PROBLEMS] To provide a method for producing tetracarboxylic acid and a method for producing tetracarboxylic dianhydride which solves the problem of low hydrolysis reaction rate of tetracarboxylic acid tetraester in the prior art. SOLUTION: The hydrolysis reaction of a tetracarboxylic acid ester is allowed to proceed at an unprecedented high reaction rate by alkali hydrolysis utilizing mechanochemistry. [Selection] Figure 1 |
