摘要:
The retentions of 72 substituted N-benzylideneanilines (NBA) in normal phase liquid chromatography were determined using seven eluents prepared with heptan, tetrahydrofuran, octanol-1, and ethyl acetate. Principal component analysis (PCA) and correspondence factor analysis (CFA) were applied to describe the behavior of the compounds. With PCA, only one factor is necessary to model the retention. CFA offers an analysis of second-order effects and shows how the retention of the relevant compounds is related to the electronic effects. A multilinear regression with the Hammett's constants of substituents is established. The influence of the substituent position on retention is discussed.
