“…The description of the chemical family of the secondary n ‐alkylamines is carried out by specifying the secondary amine NH group, which is also modeled as an associating group, but in this case it features only one association site of type e to represent the electron lone pair on the nitrogen atom and one hydrogen site of type H; only sites of different type interact. The like NH–NH and unlike NH–CH 3 , NH–CH 2 group interactions are obtained using pure‐component experimental vapor‐pressure and saturated‐liquid density data for four secondary alkylamines: diethylamine, dibutylamine, dihexylamine, and dioctylamine 57,58 …”

“…The description of the chemical family of the secondary n- and dioctylamine. 57,58 Furthermore, in order to obtain reliable estimates of the interaction between the amine and alkyl groups, experimental data for the isobaric VLE of binary mixtures of secondary alkylamines and linear alkanes are also considered. 59,60 Specifically, experimental data for diethylamine + n-hexane, 59 diethylamine + n-heptane, 59 and dipropylamine + n-hexane 60…”

The SAFT-γ Mie group-contribution equation of state is used to represent the fluid-phase behavior of aqueous solutions of a variety of linear, branched, and cyclic amines. New group interactions are developed in order to model the mixtures of interest, including the like and unlike interactions between alkyl primary, secondary, and tertiary amine groups (NH 2 , NH, N), cyclic secondary and tertiary amine groups (cNH, cN), and cyclic methine-amine groups (cCHNH, cCHN) with water (H 2 O). The group-interaction parameters are estimated from appropriate experimental thermodynamic data for pure amines and selected mixtures. By taking advantage of the group-contribution nature of the method, one can describe the fluid-phase behavior of mixtures of molecules comprising those groups over broad ranges of temperature, pressure, and composition. A number of aqueous solutions of amines are studied including linear, branched aliphatic, and cyclic amines. Liquid-liquid equilibria (LLE) bounded by lower critical solution temperatures (LCSTs) have been reported experimentally and are reproduced here with the SAFT-γ Mie approach. The main feature of the approach is the ability not only to represent accurately the experimental data employed in the parameter estimation, but also to predict the vapor-liquid, liquid-liquid, and vapor-liquid-liquid equilibria, and LCSTs with the same set of parameters. Pure compound and binary phase diagrams of diverse types of amines and their aqueous solutions are assessed in order to demonstrate the main features of the thermodynamic and fluid-phase behavior.

“…4 Molecular association via hydrogen bonding in other self-associated liquids (e.g., alcohols or amines) is reflected in response functions, especially in the isobaric heat capacity. 5,6 These phenomena are also relevant in mixtures of aqueous solutions of alcohols 7 and also in alcohol-alkane mixtures. [8][9][10][11] Some response functions are determined from others using the following two exact thermodynamic relations:…”
