In this study, we have reported a new experimental measurement of the density, viscosity, conductivity, pH, surface tension
and thermal stability of three different deep eutectic solvents- DES, Choline chloride+Monoethanolamine and ChCl-MEA;
Choline chloride+Diethanolamine, ChCl-DEA; and Choline chloride+Methyldiethanolamine, ChCl-MDEA, representing the
primary, secondary and tertiary amines, respectively. The experimental data was obtained at temperature from 293.15-353.15
K and for three different choline chloride:amine molar ratios of 1:6, 1:8 and 1:10. Results revealed that amine-based DESs are
more thermally stable as compared to stand-alone amine solvents. The density and viscosity showed a negative relationship
with temperature in the linear regression model based on the least square approach. On the other hand, the conductivity
increased linearly with increasing the temperature. The density, viscosity, stability and conductivity increased with decreasing
molar ratio of the amine in the DESs. However, there was no clear trend in the pH with molar ratio. The prepared DESs showed
very promising results in CO2 capturing.
Biography
Inas M AlNashef has joined King Saud University, Riyadh, Saudi Arabia, after obtaining his PhD degree from the University of South Carolina and further promoted
to Associate Professor. He was very active in research related to green engineering and sustainability and established collaboration with the University of Malaya,
Malaysia, where he was a Co-Advisor. Later, he moved to Abu Dhabi, UAE where he is presently working as an Associate Professor in the Department of Chemical
Engineering at Khalifa University of Science and Technology, Masdar Institute. He has also co-authored more than 80 peer-reviewed journal publications. In
addition, he received 7 patents from US and EU patent offices. He is also a recipient of several prestigious awards including King Abdullah Award for best invention
in 2013.
