Deep eutectic solvents (DESs) are a new class of green solvents that open a whole new world of opportunities for separation challenges. This book comprehensively provides a detailed discussion of their application as an extractive solvent in separation processes, adopting molecular dynamics (MD) simulations for atomistic insight into the solute transfer across bi-phasic systems. Furthermore, it explains ternary and quaternary mixtures, including MD simulation of relevant DES systems.
Features in this volume include the following
Applications of DESs in the extraction of aromatics and polyaromatics from fuel oil by liquid–liquid extraction
Eutectic behavior with respect to hydrocarbon and aqueous solutions
MD insights on extraction using DESs
Possible industrial applicability of potential DESs
Results from Gaussian, NAMD, and PACKMOL software packages
This book is aimed at researchers and graduate students working in the field of fuels and petrochemicals, separation science, chromatography, and chemical processing and design.
