Abstract: A titration of hydroxybenzophenones with sodium methoxide in a nonaqueous medium and in dimethylformamide and pyridine is described and based upon infrared spectral data, pK values and Hammett substituent constants an explanation is given why phenolic groups in positions 2 and 2,2' in 2,4-dihydroxybenzophenone and 2,2',4,4'-tetrahydroxybenzophenone resisted titration.
