PROCESS FOR THE CONTINUOUSLY OPERATED PURIFICATION BY DISTILLATION OF THE METHANOL SOLVENT USED IN THE COPRODUCT-FREE SYNTHESIS OF PROPYLENE OXIDE, WITH THE METHOXYPROPANOLS AND THE HIGH BOILERS SEPARATED OFF SIMULTANEOUSLY
Application 43/CHENP/2005 published 2007-03-30, filed 2005-01-24
Process for the continuously operated urification by distillation of the methanol used as solvent in the synthesis of propylene 0 .de by reaction of a hydroperoxide with propylene, with the methoxypropanols being separ led off simultaneously, wherein the solvent mixture obtained in the synthesis is separated in a dividing wall COIW1U1 into a low-boiling fraction comprising methanol, an intermediate-b iling fraction comprising the methoxypropanols as azeotrope with water and a high-boiling action comprising water and propylene glycol
