| titleOfInvention | 1,3-naphthalenedicarboxylic acid production method |
| abstract | 1,3-naphthalenedicarboxylic acid is prepared by liquid phase oxidation of 1,3-dialkylnaphthalene using an oxygen-containing gas in the presence of a C 2 -C 6 lower aliphatic carboxylic acid solvent and a catalyst comprising a heavy metal and a bromine compound. Are manufactured.n n n 1,3-naphthalenedicarboxylic acid is efficiently produced at low cost by controlling the ratio of the total number of atoms of bromine supplied to the reaction system to the total number of molecules of 1,3-dialkylnaphthalene supplied to the reaction system within a specific range. .n n n Starting 1,3-dialkyl prepared by isomerizing dimethylnaphthalene in the presence of a catalyst comprising hydrogen fluoride and boron trifluoride together with a C 5 -C 10 alicyclic saturated hydrocarbon having a 5- or 6-membered ring structure High purity 1,3-naphthalenedicarboxylic acid is efficiently produced using 1,3-dimethylnaphthalene which is naphthalene. |
