| titleOfInvention | Recovery method of terephthalic acid |
| abstract | In the present invention, benzoic acid is recovered from primary wastes generated in a terephthalic acid production process, then the secondary wastes are mixed and stirred in water, and the secondary wastes are dissolved in a caustic soda aqueous solution. Then, the solution is dissolved in a NaHSO 3 aqueous solution To crystallize terephthalic acid and precipitate terephthalic acid.n n n Recovery of terephthalic acid having a purity of 93% or more can be very easily recovered by the present invention. |
