Determination and structural correlation of p K BH + for meta-and para-substituted benzamides in sulfuric acid solutions

Abstract: The protonation of some meta and para substituted benzamides in sulfuric acid solutions was studied by UV spectroscopy in the 190–350 nm region. Principal component analysis was applied to separate the effect of protonation from the medium effect. The spectral region 200–350 nm was used for the calculation of the ionization ratio from coefficient… CONTINUE READING
