Verfahren zur Herstellung von Ketonen

摘要

In the process of making ketones by oxidizing olefins wherein olefins are first hydrated to secondary alcohols which are then dehydrogenated to ketones, the hydration step is carried out simultaneously with a liquid organic extraction step during which the secondary alcohols and ether by-product formed are absorbed and, following separation of the olefin-water phase, the secondary alcohols in the organic extracted phase are dehydrogenated and the ether by-product is purged.
