ABSTRACT:
In a cyanoalkylation process involving the reaction of a cyanoalkene compound such as acrylonitrile with a compound containing a labile hydrogen such as ethylene glycol, to form a cyanoalkylated product such as 3,3'-ethylenedioxybis(propionitrile), the conversion of the cyanoalkene is limited to about 60 to 96%, preferably 70 to 85%, whereby the formation of byproducts is reduced from that which is obtained when the conversion of the cyanoalkene is greater than about 96%.
