| titleOfInvention | Method for producing naphthalenecarboxylic acid with excellent filterability |
| abstract | (57) [Summary] [Structure] A substituted naphthalene was extracted from a reactor in a method for producing a naphthalenecarboxylic acid by continuously oxidizing with molecular oxygen in an acetic acid solvent in the presence of an oxidation catalyst containing a heavy metal. The reaction solution containing the reaction product is taken out of the system while gradually lowering the temperature and lowering the pressure using two or more receiving tanks, and at that time, the pressure of at least the first receiving tank is set to 1 Hold at / 5 or more. [Effect] A high-purity product having good filterability can be obtained in good yield. |
