Title

Unravelling the interactions of hydrophobic deep eutectic solvents with water (Cont.)

Abstract

In the recent years, the search for "green solvents" has been intensified and Deep Eutectic Solvents (DESs) have been emerged as na alternative to conventional molecular solvents. DESs are formed by the association of an hydrogen bond acceptor with an hydrogen bond donor. In the eutectic composition, the mixture has a melting point much lower than that of an ideal mixture of its components. However, the high viscosity of DESs may hinder their practical applications in different industrial processes. The viscosity of DES systems was found to decrease significantly with the addition of even small amounts of water. Thus, the effect of water on the nanostructural properties of DESs is of utmost importance. Having a firm grasp of how water interacts with binary eutectic mixtures is an essential prerequisite for the design of hydrated DES systems suitable for defined applications - such as food processing, extraction processes, enzyme reactions, and pharmaceutical uses. This project aims at the understanding of the behaviour of DES with hydrophobic components as a function of increasing water content, using Inelastic Neutron Scattering.
