The effects of p-substitution on certain properties of the N–H bond in aniline have been examined in this experimental study. The dipole moments and NH group stretching frequencies of aniline, p-anisidine, p-toluidine, p-chloroaniline, p-bromoaniline and p-cyanoaniline have been determined in cyclohexane and dioxan and the affinity of these compounds for dioxan in solution, and for an activated alumina adsorbent at the solution–solid interface assessed. Dipole moments have been calculated from measurements of dielectric constant, refractive index and density of a series of solutions of graded concentration. The affinity of the anilines for dioxan have been determined from measurements of optical density in the ultra-violet region of the spectrum. [Continues.]
