Excess enthalpies of alkanediamines+benzene or + toluene mixtures

Measurement and prediction of (solid+liquid) equilibria of (alkanediamine+biphenyl) mixtures

“…For modified UNIFAC, values of the required geometrical and interaction parameters of our systems have been given elsewhere [22,23]. In the DISQUAC model [15,24], the diamines are regarded as possessing two types of surfaces: type a, alkane (CH 3 or CH 2 group), type n, amine (NH 2 group). The biphenyl presents a surface type b (C 6 H 5 group).…”

“…The biphenyl presents a surface type b (C 6 H 5 group). The geometrical and interchange parameters have been estimated previously [15].…”

“…Following our systematic study of the thermodynamic properties of mixtures of tertiary diamines with n-heptane, or cyclohexane [12][13][14], and primary diamines with benzene, or toluene [15], and (solid + liquid) equilibrium of diamines with n-alkanes [16], it seemed interesting to test the application of DSC to the determination of SLE of complex systems including polyaromatics and alkane-a,xdiamines.…”

Solid−Liquid Equilibria of Naphthalene + Alkanediamine Mixtures

“…To further our systematic study of the thermodynamic properties and solid−liquid equilibrium of mixtures of diamines, − it seemed interesting to test the application of DSC to the determination of SLE of complex systems including polyaromatics and alkane-α,ω-diamines.…”

“…Among the methods of SLE measurement, it was shown that differential scanning calorimetry (DSC) is a rapid and sensitive technique, broadly used for the characterization of many kinds of phase change. [7][8][9][10] To further our systematic study of the thermodynamic properties and solid-liquid equilibrium of mixtures of diamines, [11][12][13][14][15] it seemed interesting to test the application of DSC to the determination of SLE of complex systems including polyaromatics and alkane-R,ω-diamines.…”
