Polarization and Polarizability of the Binary Mixtures of Tetraethylene Glycol With Benzene and Toluene at 20°C and 30°C

Abstract

The refractive index of the binary mixtures of tetraethylene glycol (TETEG) with benzene and toluene at 20°C and 30°C and atmospheric pressure have been measured at the whole composition range of mixtures. The polarizabiltiy (α), atomic polarization (P_a), solvated radii (r), and excess refractive indices (n^DE) were calculated and represented in figures versus concentration.

Keywords:

• atomic polarization
• polarizability
• refractive index
• and solvated radii
