Hydracrylonitrile → Bis(2-cyanoethyl) ether

Participants

Reaction Steps

The reaction mixture is advantageously worked up by the following procedure: the 3-dialkylaminopropionitrile I together with the water and the byproduct ethylenecyanohydrin III is isolated, for example, with the aid of a thin film evaporator. Thereafter, the remaining high boiling mixture is neutralized with a dilute mineral acid and the bis-(2-cyanoethyl) ether II is isolated from this mixture by fractional distillation under reduced pressure.
