Reaction Steps

An aqueous solution of disodium terephthalate, passed through adsorption tower (4), was transferred to neutralization tank (5). Then, the solution was stirred by agitator (5a) in neutralization tank and added slowly with 97% sulfuric acid and incessantly until the pH of solution became 4.0. As a result of monitoring by SEM, the particle size of terephthalic acid formed from said neutralization process, its particle size (10 to 20 μm) was very small.
