Abstract
Acrylonitrile is converted to a dimer product, at least 85% by weight of which consists of 1,4-dicyanobutenes, by reacting with an organic phosphite catalyst in a liquid solvent for the catalyst comprising an organic proton donor and substantially devoid of water, the acrylonitrile forming less than 50% by weight of the total liquid reaction mixture.
