Abstract
PURPOSE: To obtain an aromatic hydroxyl compound continuously, by alkali fusion of an aromatic sulfonic acid while making the reaction mixture overflow from the reactor together with water naturally.
CONSTITUTION: An aromatic sulfonic acid or its alkali metal salt and caustic alkali are fed from the nozzles 1 and 6 into the reactor 2 continuously, and reacted at 300W450°C while being agitated with the agitating blade 4. By-products or water fed into the reaction zone with the raw materials is made to overflow from the nozzle 5 naturally together with the reaction mixture to prepare an aromatic hydroxyl compound continuously.
