Study of self-association of t-butyl alcohol by linear and non-linear dielectric effects

Abstract

A method for the simultaneous determination of three independent values of the free energy of self-association from experimental dielectric data is proposed. This involves the determination of ΔG, ΔH and ΔS for linear bond formation in open multimers, for bond formation in cyclic trimers and in higher cyclic multimers of t-butanol. The proposed method allows one to evaluate the relative concentrations of open and cyclic structures with great accuracy. Moreover, it can determine which of the possible models of association describes the experimental system being tested.
