A process for the recovery of neopentyl glycol by cleaving incurred in manufacturing high boilers

A process for the recovery of neopentyl glycol from the obtained in the reaction of formaldehyde with isobutyraldehyde high boilers, characterized in that the high boilers are separated from the process for the preparation of neopentyl glycol and in a separate hydrogenation reactor solvent in the presence of a copper-chromite catalyst at a temperature of 140 to 220 ° C and at a pressure of 7 to 28 MPa are treated with hydrogen in the liquid phase and the cleavage products obtained are worked up by distillation.
