摘要： Highly pure, less colored aromatic polycarboxylic acids are produced from crude aromatic polycarboxylic acids by simple procedures at low production costs. The crude aromatic polycarboxylic acid is mixed with aliphatic amine or alicyclic amine in the presence of a solvent to precipitate crystals of amine salt of aromatic polycarboxylic acid. The crystals are dissolved in water and decomposed, thereby obtaining the highly pure aromatic polycarboxylic acids.

摘要： A process for producing highly pure 2,6-dimethylnaphthalene in a high yield from a mixture of dimethylnaphthalene isomers in the presence of a solvent, such as an aliphatic or alicyclic saturated hydrocarbon. Highly pure 2,6-dimethylnaphthalene can be produced steadily for a long time by filtering the 2,6-dimethylnaphthalene crystal precipitated by the crystallizing by using a filtration apparatus, such as a rotary vacuum filter, peeling-off the filtered cake from a filter cloth and cleaning the filter cloth with a solvent, at a temperature not lower than a filtration temperature.

摘要： There are disclosed an industrially advantageous process for efficiently producing highly pure 2,6-dimethylnaphthalene (DMN) in high yield from a mixture of DMN by carrying out in turn, the steps of isomerizing a mixture of DMN in the presence of a catalyst; crystallizing the isomerization reaction product in the presence of a solvent (e.g. an aliphatic or alicyclic saturated hydrocarbon) to precipitate 2,6-DMN crystal; isolating and recovering the 2,6-DMN thus precipitated; and distilling the mother liquor formed after the isolation of the crystal to obtain DMN fraction by removing the components having a higher boiling point than DMN and the components having a lower boiling point than DMN, while at least part of the DMN fraction is returned to the isomerization step and circulated through the process; a process for producing a 2,6-naphthalenedicarboxylic acid by subjecting the 2,6-DMN obtained by the above process to liquid-phase oxidation; and a process for producing 2,6-naphthalenedicarboxylic acid ester by esterifying 2,6-naphthalenedicarboxylic acid thus produced.
