Solubility of CO2 in a Choline Chloride Urea Eutectic Mixture

Recent Advances in Solvents for the Dissolution Shaping

These ionic fluids are obtained by mixing hydrogen bond acceptors e g choline chloride (ChCl) with hydrogen bond donors e g amides such as urea In principle they can be viewed as a type of mixed ILs too but since they do not consist exclusively of ions the term DES was introduced to distinguish between both classes of fluids [ 224 ]

Effect of Water on the Density Viscosity and CO2

To study the effect of water on the properties of choline chloride (ChCl)/urea mixtures (1:2 on a molar basis) the density and viscosity of ChCl/urea (1:2) with water were measured at temperatures from 298 15 K to 333 15 K at atmospheric pressure the CO2 solubility in ChCl/urea (1:2) with water was determined at 308 2 K 318 2 K and 328 2 K and at pressures up to 4 5 MPa

Deep eutectic solvent

Deep eutectic solvents are systems formed from a eutectic mixture of Lewis or Brnsted acids and bases which can contain a variety of anionic and/or cationic species They are classified as types of ionic solvents with special properties They incorporate one or more compound in a mixture form to give a eutectic with a melting point much lower than either of the individual components
