Dielectric Relaxation of Binary Mixtures of Glycerol with Three Monohydric Alcohols

Abstract

The dielectric spectra of the following liquid mixture systems have been measured over the whole absorption region: Glycerol (Gly)/n-butanol, Glylr-butanol (both at 20°C) and Gly/guaiacol(20,40 and 60 " C ) . Thc results are comparatively discussed with regard to hetero-interactions, taking into consideration the possibility of internal hydrogen bonding in the case of guaiacol and. generally. of steric constraints.

Dielectric relaxation study of aniline,N-methylaniline andN,N-dimethylaniline and alcohol in 1, 4-dioxane using picosecond time-domain reflectometry

“…As dipole moment of solvent (dioxane) is very small (μ = 0.97D), [17] the interaction between third pair can be neglected. Therefore, interaction between co-solvent-dioxane [18][19][20][21][22][23][24][25] can provide insight to understanding the exact nature of -OH group through molecular interaction in the liquid. S. Czerkas et al [24] have reported the variation of viscosity and activation energy against mole fraction of alcohol in dioxane.…”
