Dielectric Properties of the Liquid Phase of Higher Alkanols on the Line of Vapor–Liquid Equilibrium

Abstract

The static dielectric permittivities of higher 1-alkanols at temperatures above the boiling point are measured. The design of the device’s cell and the device itself are examined in detail. Results obtained by other authors are analyzed. Temperature dependences es(Т) of the static dielectric constants, of liquids with and without hydrogen (H-) bonds are compared at the vapor–liquid equilibrium line in the vicinity of the critical temperature. The requirements for selecting the geometry of the angle of O–H···O–H association in molecular dynamics (MD) models are analyzed to accurately describe the experimental static permittivities of 1-alkanols.
