Abstract

Cyclobutane-1,2-dinitrile is produced by irradiating acrylonitrile, with or without the addition of a polymerization inhibitor or a neutral solvent, with visible light and/or U.V. light and separating the cyclobutane-1,2-dinitrile from the resulting mixture there being added to the acrylonitrile as photo-sensitizer benzaldehyde or a derivative thereof, or g -pyrone or its homologues or benzo derivatives. The photo-sensitizer may be a benzaldehyde of the general formula <FORM:1095849/C2/1> in which R1 and R2 are the same or different and each represents hydrogen or a halogen or an alkyl, aryl, cyano or ester group. Preferred photo-sensitizers are p-tolualdehyde, p - bromo-benzaldehyde, 2,6 - dimethyl - g - pyrone and xanthone.
