Abstract: A PROCESS FOR THE PREPARATION OF E-CAPROLACTONE WHICH COMPRISES HEATING AT LEAST ONE AMIDE SELECTED FROM THE GROUP CONSISTING OF E-HYDROXYCAPROAMIDE AND AMIDES OF LOW POLYMERIZATION PRODUCTS OF E-HYDROXYCAPROIC ACID, IN THE PRESENCE OF AN ALCOHOLIC COMPOUND CONTAINING AT LEAST ONE FREE ALCOHOLIC HYDROXYL GROUP IN ITS MOLECULE, IN AN AMOUNT SUCH THAT, WHEN ONE E-HYDROXYCAPROIC ACID UNIT OF THE FORMULA #O-(CH2)5CO$ CONTAINED IN THE AMIDE IS CALCULATED AS ONE MOLECULE OF E-HYDROXYCAPROIC ACID, THE TOTAL NUMBER OF FREE ALCOHOLIC HYDROXYL GROUPS PRESENT IN THE REACTION SYSTEM EXCEEDS THE TOTAL NUMBER OF CARBOXYL GROUPS PRESENT IN THE REACTION SYSTEM, UNDER SUCH TEMPERATURE AND PRESSURE CONDITIONS TO ALLOW DISTILLATION OF E-CAPROLACTONE.
