Expand: In the purification of light benzoic acid, thiophene reacts with sulfuric acid to form thiophene sulfonic acid dissolved in the waste sulfuric acid, clarifying the waste sulfuric acid, removing the tar substance, and then hydrolysis distillation. The distillates are cooled and separated by condensation, and crude distillates containing thiophene and benzenes can be obtained. After alkali neutralization or neutralization of crude distillation, the theory is used.
