- W1986101514 abstract "On étudie en solution dans le bénzène, les mélanges de la pyridine, l'aniline et les 2 et 3-aminopyridine avec le phénol, le 1,3 et le 2,3-dihydroxynaphtalène. La comparaison des valeurs des constantes d'association obtenues par mesures diélectriques montre que, pour les aminopyrilines, la liaison hydrogène est assurée par l'atome d'azote du cycle et que dans les cas du mélange 3-aminopyridine-2,3-dihydroxynaphtalène, il y a possibilité d'une association par double liaison hydrogène. Ces résultats sont confirmés par l'étude infrarouge des vibrations du groupement NH2. We have studied the mixtures of pyridine, aniline, and 2 and 3-aminopyridine with phenol, 1,3 and 2,3-dihydroxynaphtalene in benzene. The comparison of the values of association constants obtained by dielectric measurements, shows that, for the aminopyridines, the hydrogen bond is formed by the nitrogen atom of the ring and that, in the case of the 3-aminopyridine-2,3-dihydroxynaphtalene mixture, there is the possibility of association by double hydrogen bond. These results are confirmed by the infrared study of the vibration of NH2 group." @default.
