The ionization constants of the conjugated acids BH+ of aniline, N-methyl- and N,N-dimethylaniline, and pyridine have been determined potentiometrically in Me2SO. The heats of neutralization of the amines B and their heats of solution have been obtained by calorimetry. The pK's and enthalpies...
A calorimetric basicity scale for six anilines and two pyridines in liquid phase is presented. The substantial effects influencing the basicity order were found to be: (1) substituent effect; (2) steric effect; (3) tautomeric effect; (4) hydrogen bond effect. This scale emphasizes the ...

The anomalous behaviour of 2,3-(COOH) 2py in a calorimetric basicity scale found for six anilines and two pyridines, is studied. A feature of this compound is the prevalence of the primary steric effect in water-rich solutions and of the substituent effect in DMSO-rich solutions. This ...
antimicrobial, antiviral, an- tioxidant, anti-inflammatory, antiamoebic, antidiabetic, antimalarial and anti-psychotic medicinal properties, hence are a part of many drugs and found to enhance pharmacologi- cal characteristics of the drugs because of their weak basicity and aqueous solubility [29]....
