METHOD FOR THE CONTINUOUS PURIFICATION BY DISTILLATION OF METHANOL, USED AS A SOLVENT IN THE SYNTHESIS OF PROPYLENE OXIDE WITHOUT COUPLING PRODUCTS, WITH THE SIMULTANEOUS ISOLATION OF THE METHOXY PROPANOLS

摘要

A kind of method of the present invention purifies methanol for continuous still, is reacted by hydroperoxides with propylene as solvent synthesizing epoxypropane, has while separating methoxypropanol as azeotropic mixture and water, in addition to low and high boiler. The method is characterized in that collecting in the synthesis to be separated in tired solvent mixture divided wall column.
