Abstract

A PROCESS FOR PRODUCING AN ALKYLENE GLYCOL, WHICH IS A CONTINUOUS PROCESS FOR PRODUCING AN ALKYLENE GLYCOL COMPRISING THE FOLLOWING STEPS (1) TO (4), WHEREIN THE HYDROLYSIS STEP (2) IS DIVIDED INTO A PLURALITY OF STAGES, AND THE HYDROLYSIS IS CARRIED OUT SO THAT THE WATER CONCENTRATION IN A REACTION STAGES WHEREIN THE CONVERSION OF THE ALKYLENE CARBONATE IS AT LEAST 60, IS FROM 15 TO 30WT: (1) A CARBONATING STEP (1-7) OF REACTING AN ALKYLENE OXIDE WITH CARBON DIOXIDE GAS IN THE PRESENCE OF A CARBONATING CATALYST TO FORM A REACTION SOLUTION CONTAINING AN ALKYLENE CARBONATE, (2) A HYDROLYSIS STEP (8, 11 - 13) OF HYDROLYZING THE REACTION SOLUTION OBTAINED IN STEP (1) WHILE RELEASING CARBON DIOXIDE GAS, TO FORM AN AQUEOUS ALKYLENE GLYCOL SOLUTION, (3) A DISTILLATION STEP (9,10) OF DISTILLING THE AQUEOUS ALKYLENE GLYCOL SOLUTION TO OBTAIN AT LEAST A DEHYDRATED ALKYLENE GLYCOL AND A SOLUTION CONTAINING THE CARBONATING CATALYST, AND (4) A RECYCLING STEP OF SUPPLYING THE SOLUTION CONTAINING CATALYST TO THE CARBONATING STEP (1)
