Abstract: THE INVENTION RELATES TO A METHOD FOR PRODUCING PURE TRIETHANOLAMINE (TEOA) BY CONTINUOUSLY SEPARATING AN ETHANOLAMINE MIXTURE CONTAINING TEOA AND DIETHANOLAMINE (DEOA) BY DISTILLATION, WHEREIN IN A DISTILLATION COLUMN (DEOA COLUMN), DEOA IS DISTILLED OFF AND THE ARISING BOTTOM FLOW CONTAINING TEOA IS FED TO A DOWNSTREAM COLUMN (TEOA COLUMN), IN WHICH THE PURE TEOA IS REMOVED AS A SIDE DRAW FLOW, WHEREIN THE RESIDENCE TIME OF THE ETHANOLAMINE MIXTURE IN THE SUMP OF THE DEOA COLUMN IS
