Abstract: Pure acetonitrile is recovered from aqueous acetonitrile by extracting with an organic solvent which has little miscibility with water, boils higher than acetonitrile and does not form an azeotrope with acetonitrile. The portion of the extract boiling up to 76*C is distilled off. The remaining acetonitrile containing more difficulty volatile portion is freed from the residual water by addition of an entraining agent and recovering the pure acetonitrile by a fractional distillation.

Abstract translation: 通过用与水混溶性小的有机溶剂提取，从乙腈水溶液中回收纯乙腈，沸点高于乙腈，不与乙腈形成共沸物。 将沸腾至76℃的提取物部分蒸馏掉。 通过加入夹带剂将含有更难挥发性部分的剩余乙腈从残余水中除去，并通过分馏回收纯乙腈。
