Özet:

 


The present study aimed to determine the refractive
indices at 293.15 K and density data at T= (283.15, 293.15, 303.15 and 313.15)
K of the binary mixtures of 1-ethyl-3-methylimidazolium ethylphosphonate + methanol or 2-propanol
under the atmospheric pressure. The excess molar volume, the apparent molar
volume, the partial molar and excess partial molar volumes of the components at
infinite dilution were calculated from the experimental values. The results of
excess molar volumes were fitted to a Redlich– Kister equation, leading thus to
obtain the coefficients and to estimate the standard deviations between the
experimental and the calculated quantities. Also, the results of excess molar
volumes of the two investigated binary mixtures showed negative deviations from
ideal behavior of the investigated binary systems which can be then discussed in
terms of ion-dipole interactions, formation of hydrogen bonds and structural
factors. Additionally, the refractive indices measurements and the deviations
of refractive index were determined.

La présente étude visait à déterminer les indices de réfraction à 293,15 K et les données de densité à T = (283,15, 293,15, 303,15 et 313,15) K des mélanges binaires de 1- éthyl - 3 - méthylimidazoliuméthylphosphonate + méthanol ou 2-propanol sous la pression atmosphérique. Le volume molaire en excès, le volume molaire apparent, les volumes molaires partiels et les volumes molaires partiels en excès des composants à dilution infinie ont été calculés à partir des valeurs expérimentales. Les résultats des volumes molaires en excès ont été ajustés à une équation de Redlich-Kister, conduisant ainsi à obtenir les coefficients et à estimer les écarts-types entre les quantités expérimentale et calculée. En outre, les résultats des volumes molaires en excès des deux mélanges binaires étudiés ont montré des écarts négatifs par rapport au comportement idéal des systèmes binaires étudiés, qui peuvent ensuite être discutés en termes d’interactions ion-dipôle, de formation de liaisons hydrogène et de facteurs structurels. . Additionally, the refractive indices measurements
and the deviations of refractive index were determined.
