    摘要: A process for the purification of crude cyanohydrins which contain 3 to 6 carbon atoms, especially of crude acetone cyanohydrin, by distilling off the unreacted reactants namely hydrogen cyanide and the carbonyl compound. The purification becomes very simple, and the unreacted reactants can be fed directly into the cyanohydrin synthesis, when the vacuum is generated with a liquid jet pump. The exhaust vapors arising in the distillation or desorption are led into the driving jet of the pump, the liquid jet pump is driven with crude cyanohydrin which contains basic catalyst, and the exhaust vapors absorbed in the crude cyanohydrin are reacted to completion in a cooled reaction circuit in which the liquid jet pump is incorporated.
