Title: Production of catechol
Inventor: NISHIDA YOICHI
IPC: C07C37/74
Filed: 1992-05-26
Abstract: PURPOSE:To obtain catechol having a high quality in good productivity by oxidizing phenol with hydrogen peroxide containing a phosphoric acid component in the presence of a ketone to produce catechol and hydroquinone, passing the reaction solution through an adsorbent for the removal of the phosphoric acid and subsequently distilling the remaining solution. CONSTITUTION:Phenol, a ketone and hydrogen peroxide containing a phosphoric acid component are fed together with a catalyst solution into the first reaction tank 1, subjected to an oxidation reaction at a reaction temperature of 75-85 deg.C to produce catechol and hydroquinone. The catechol-produced reaction solution is transferred to the first solution-receiving tank 3 and stored. The reaction solution is subsequently fed into one of the first filled tower 4 and the second filling tower 5 both filled with an absorbent such as active carbon to adsorb off the phosphoric acid component. When the filled tower sufficiently adsorbs the phosphoric acid component to lower the adsorption activity of the filled tower, the filled tower is switched into the other filled tower having the high adsorbing ability, and the adsorption tower lowered in the adsorbing ability is regenerated. The processes are successively repeated to remove the phosphoric acid component. The remaining solution is transferred to the second solution-receiving tank 6 and then distillation-purified to obtain catechol.
