Gas Chromatographic Retention Indices of 2-chlorobenzylidenemalononitrile and its Analogues
Riot control agent, 2-chlorobenzylidenemalononitrile (CS) and its analogues have both skin irritating and lacrymating properties. Herein, we report retention indices (RI) of CS and its thirteen analogues relative to the homologues n-alkanes series. These values are determined on nonpolar BP-1 and polar BP-10 capillary column under programmed temperature and isothermal chromatographic condition. The analogues differ in substitution at ortho or para position of phenyl ring and retention indices are found to vary according to the nature of the substituent.
