Abstract
The separation of aromatics and aliphatic from the hydrocarbon mixture stands a significant challenge. In this manuscript we present atomistic molecular dynamic simulations to understand the structure and separation thermodynamic properties of BTX (Benzene, toluene, xylene) from n-heptane using ionic liquids. Here we considered the amino acid derived ionic liquid considering the tetra butyl phosphonium as cation and valine anion at three different temperatures 298 K, 323 K and 348 K. We observe that IL show strong intermolecular structure with BEN (benzene) when compared to TOL (toluene) and XYL (p-xylene). Based on the solvation free energy (ΔGsolv), transfer free energy (ΔGtransfer) and partition coefficient (log P) analysis of BEN show favourable for the transfer from n-heptane to IL phase when compared to TOL and XYL. Overall results presented in this paper provide molecular level understanding of the design of amino acid-based IL for the separation BTX from the hydrocarbon mixture.
