Method of producing terephthalic acid |
| abstract |
A method of terephthalic acid production in which slurry of crude terephthalic acid obtained through liquid-phase oxidation of a p-phenylene compound or a terephthalic acid slurry resulting from catalytic hydrogenation of the crude terephthalic acid is introduced into an upper part of a dispersion medium replacement tower while a second dispersion medium for replacement is introduced from a lower part of the dispersion medium replacement tower to perform dispersion medium replacement. The method is capable of enabling the dispersion medium replacement tower to continue stable operation while maintaining an extremely high efficiency of dispersion medium replacement. |
