At total, 31 new model parameters were estimated with a local search algorithm based on 2960 binary vapor-liquid equilibrium experimental points. Other necessary parameters (water, alkanes, ethers, aromatics and alcohols) were reused unchanged from previous F-SAC works. In order to describe the same mixtures, UNIFAC\u00a0(Do) contains 230 non-zero binary parameters. The F-SAC model was able to correlate the data with 3.64% mean relative deviation, which is superior to the UNIFAC (Do) response with literature parameters. Furthermore,\u00a0alkanolamines\u00a0and\u00a0morpholine\u00a0were well described reusing alcohol and cyclic ether groups.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0378381218304576\">Access the full article on this link.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this work the F-SAC model was extended to describe aqueous and organic mixtures containing amines.
