실험 절차
An aqueous solution of disodium terephthalate, passed through adsorption tower (2), was transferred to neutralization tank (3). Then, the solution was stirred by agitator (3a) in neutralization tank and added slowly with sulfuric acid and incessantly until the pH of reaction solution was 2.0. As a result of monitoring by SEM the particle of terephthalic acid formed from said neutralization process, its particle size (10 to 15 μm) was very small.
