Dielectric Measurements of the Ternary Mixtures of Alcohols With Aniline in Carbon Tetrachloride at 301k

Abstract

The nature of hydroxylamine complexes was identified through the formation of hydrogen bonding between alcohols (methanol, ethanol, propanol, and butanol) with aniline from the dielectric measurements like dielectric constant, density and refractive index. From these measurements, the dipole moment of hydroxylamine complex was determined from the Huysken's method origin of Onsager model also evaluated the dipolar increment. The enthalpy changes due to bond formation obtained from the dipolar increment. The dipole moment of the both cis and trans structure are determined and tabulated, the dipole moment values of the trans are higher than the cis structure it may complex is form the trans structure. The value of dipole moment of the complex, dipolar increment and enthalpy changes concluded complex formation mainly due to the polarization only. These values indicate the order of the complex methanol > ethanol > propanol > butanol, aniline as one of the component.
