Abstract: Using p-phenylene-di-n-alkoxybenzoate homologous series as stationary liquid, the infinite dilution activity coefficients γ_i~∞, partial molar excess enthalpies H_i~E and entropies S_i~E of xylene isomers, dichlorobenzene isomers, diphenyl and diphenylmethane have been measured in the nematic phase of three liquid crystals. The studied liquid crystal series have the following general formulas,
where n=6(PBH_xB), n=7(PBH_pB) and n=8(PBOB)
The results were explained from theview point of statistical theory of solutions.
