Theoretische und experimentelle Untersuchungen über die Mischungseffekte von Benzol mit seinen Quasi-Dimeren Diphenyl, o,ο'-Ditolyl und Diphenylmethan

Abstract

Explicit formulae for the excess functions of monomer-dimer mixtures based on the “average potential model” are given. Values of the heat of mixing at 35°C of the system benzene-diphenylmethane determined by means of a sensitive quasi-isothermal differential calorimeter are reported and constructional details and properties of the calorimeter are described. Experimental and theoretical values of the mixtures benzene-diphenyl, benzene-o,o'-bitolyl and benzene-diphenylmethane are compared and the deviations are discussed.
