HCID 174Ethylene GlycolSolvent

Procedure

Next, 166 parts by mass of the obtained terephthalic acid/water slurry and 4150 parts by mass of ethylene glycol were placed in a centrifuge and mixed. The ratio by mass of the terephthalic acid/water/ethylene glycol was 1:1:50 at the point of being placed therein, and the solvent was removed from the slurry to yield a terephthalic acid cake. The ratio by mass of the terephthalic acid/water/ethylene glycol in the terephthalic acid cake was approximately 83:0.4:14.3.
