Orientational entropy and dipolar aggregation in mixtures of propylene carbonate + N , N -dimethylacetamide

Thermodynamics of amide + amine mixtures. 4. Relative permittivities of N,N-dimethylacetamide + N-propylpropan-1-amine, + N-butylbutan-1-amine, + butan-1-amine, or + hexan-1-amine systems and of N,N-dimethylformamide + aniline mixture at several temperatures. Characterization of amine + amide systems using ERAS

“…Of particular interest is the investigation of entropic effects induced in the liquid by the external electric field applied, E . The relationship between r ( / ) T ε ∂ ∂ and the entropy increment per volume unit is given by [28,[53][54][55]:…”

“…∆ magnitude as then one is considering along the discussion a number of molecules equal to A N [54,55]. Within this treatment, volume variations with T have been neglected.…”
