Experimental (solid+liquid) or (liquid+liquid) phase equilibria of (amine+nitrile) binary mixtures

Experimental (solid+liquid) phase equilibria of (alkan-1-ol+benzonitrile), (amine+benzonitrile) binary mixtures, and (decan-1-ol+decylamine+benzonitrile) ternary mixtures

“…Eutectic points of these systems are listed in Table 2. Our results on SLE of {amine (1) + benzonitrile (2)} systems are very similar to results published earlier for {amine (1) + acetonitrile (2)} [6]. Simple eutectic systems, with the eutectic point shifted to the lower amine mole fraction for the longer alkyl chain length of amine, have been observed (see Table 3 and Fig.…”

“…Simple eutectic behavior was observed for these mixtures [6]. Also LLE phase diagrams have been determined for (octylamine, or decylamine + propanenitrile, or + butanenitrile) [6].…”

“…This paper is a continuation of our systematic study on the interactions between unlike molecules in systems of polar compounds, such as alkan-1-ols with amines [1][2][3][4], mixtures of alkan-1-ols with nitriles [5] and amines with nitriles [6]. Mixtures of (alkan-1-ol, or amine + nitrile) are known from the heats of mixing and excess molar volumes to show weaker interactions, than that observed in (alkan-1-ol + amine), especially for the short chain alcohols, or amines (see Refs.…”

“…The choose of substances was dictated by the method of measurements (melting temperatures possible to observed). Additionally, the same solvents were used as in our previous work [1][2][3][4][5][6].…”

“…To close our fundamental discussion about the interactions in these polar systems [1][2][3][4][5][6], SLE for the ternary system (decan-1-ol + decylamine + benzonitrile) have been determined at three temperatures 273.15, 278.15 and 283.15 K using the same cryometric dynamic method at atmospheric pressure.…”
