| titleOfInvention | Method for producing biphenyltetracarboxylic acid tetraester |
| abstract | PROBLEM TO BE SOLVED: To oxidatively couple a phthalate ester using a catalyst containing palladium in the presence of molecular oxygen to produce a biphenyltetracarboxylic acid tetraester, particularly 2,3,3 ', 4'-biphenyltetracarboxylic acid tetra A more economical production method for selectively producing asymmetric biphenyltetracarboxylic acid tetraesters such as esters is provided. In a process for producing a biphenyltetracarboxylic acid tetraester in which phthalic acid diester is oxidatively coupled using a catalyst containing at least a palladium salt, a copper salt and a β-dicarbonyl compound in the presence of molecular oxygen, β- A biphenyl compound having a specific chemical structure and having an enol ratio exceeding 80% measured at 26 ° C. in a solution state dissolved in dimethyl phthalate at a concentration of 0.1 mol / L as a dicarbonyl compound. The present invention relates to a method for producing tetracarboxylic acid tetraesters. [Selection figure] None |
