Original Abstract

The acid-base properties of 19 2,4-disubstituted 6-morpholinomethylphenols were studied by means of potentiometric and/or spectrophotometric titration. The evaluated pI values were correlated with Hammett sigma-meta and sigma-para constants for 2-X and 4-Y substituents, respectively. A DSP equation fits adequately (r= 0.993) the wide range of pI values from 4.8 to 9.1 without any deviation due to an intramolecular H-bonding of ortho NO2 groups.
