Densities, speed of sound, and IR studies of Ethyl lactate with 2-alkoxyethanols at different temperatures

Thermodynamic Excess Properties and FTIR Spectroscopic Studies of Binary Mixtures Containing Propiophenone and 2- Alkoxy Ethanolsat Temperatures 303.15K, 308.15K, 313.5Kand 318.15K

“…The purities of the liquids were checked by comparing the values of densities and ultrasonic velocities with literature data and are given in Table-01b. a [3], b [4], c [5], d [6], e [7], f [8], g [9], h[10], i [11], j [12], k [13], l [14] Proper care was taken to avoid any evaporation loss while doing the experiment. The densities of liquids and their mixtures were measured using bi-capillary pycnometer having a capillary diameter of 0.85 mm, which was calibrated using double distilled water.…”

“…The Excess molar volume (V m E ) values depends upon three factors mainly physical, chemical and structural properties. The sign and magnitude of the excess properties depend on the following factors [7]: (i) The disruption of dipolar molecules in the like associated molecules is due to the addition of second component molecule. (ii) Chemical association between unlike molecules through the formation of hydrogen bond, which is a strong specific interaction, (iii) Association through weaker physical forces like dipole-dipole interaction and (iv) Accommodation of molecules of one component in to the interstitial positions of the structural network of molecules of other component.…”

Acoustic, Volumetric and Viscometric Studies of Binary Liquid Mixtures of p-Chloroacetophenone with n-Alkanols at Different Temperatures

“…The intermolecular interactions are formed between the oxygen atom of -OH group of alcohols and the carbonyl group of p-chloroacetophenone 9 . Excess molar volumes (V E ) depends on some important factors like 10 .…”

Comparative studies of intermolecular interaction of aromatic amines with ethyl lactate at different temperatures

“…In continuation of our work on thermodynamic properties of binary liquid mixtures [10][11][12][13] we present densities and speeds of sound for binary mixtures of ethyl lactate and aromatic amines at four different temperatures T = (303. 15 [14].…”
