Abstract: TRIMETHYLOLPROPANE IS ISOLATED FROM A REACTION MIXTURE WHICH HAS BEEN OBTAINED BY REACTION OF N-BUTYRALDEHYDE WITH FORMALDEHDE IN THE PRESENCE OF A BASE AND, IF APPROPRIATE, HYDROGENATION OF THE RESULTING MIXTURE BY DISTILLING THE MIXTURE BY MEANS OF A DIVIDING WALL COLUMN OR A DISTILLATION COLUMN WITH A PRECOLUMN OR A DISTILLATION COLUMN WITH AN AFTER-COLUMN. THE PROCESS HAS LOW CAPITAL COSTS AND A LOW ENERGY CONSUMPTION AND GIVES REDUCED FORMATION OF HIGH-BOILING BY-PRODUCTS.
