Abstract
The solvatochromic hydrogen bond donor (HBD) acidity parameter (a(mix) ) of aqueous mixtures of methanol, acetonitrile, propan-2-ol and tetra hydrofuran were determined spectrophotometrically. The study was carri ed out at 25 degrees C as a function of composition, The indicators us ed were -diphenyl-4-(2,4,6-triphenyl-N-pyridino)phenolate, 6-dichloro- 4-(2,4,6-triphenyl-N-pyridino)phenolate and Fe(LL)(2)(CN)(2) (LL = N-( 2-pyridylbenzylidene)-3,4-dimethylaniline), The HBD acidity of the aqu eous organic mixtures was related to retention in reversed-phase liqui d chromatography.
