Zhu, Chenyang Xue, Sa Ikram, Rana Liu, Xiangyang He, Maogang Experimental Study on Isobaric Molar Heat Capacities of a Deep Eutectic Solvent: Choline Chloride + Ethylene Glycol In this study, a flow calorimeter is used to measure the isobaric molar heat capacities (<i>C</i><sub><i>p</i></sub>) of one deep eutectic solvent (DES) containing choline chloride and ethylene glycol at different molar ratios. The experiment is performed at temperatures from 313 to 343 K and pressures up to 25 MPa, while the expanded uncertainties of temperature, pressure, molar fraction, and <i>C</i><sub><i>p</i></sub> are estimated to be lower than 0.02 K, 5.0 kPa, 1.4 × 10<sup>–4</sup>, and 1.28%, respectively. The results show that <i>C</i><sub><i>p</i></sub> change linearly with temperature, while it is almost constant with a variety of pressure. A quadratic relation between <i>C</i><sub><i>p</i></sub> and molar fraction of ethylene glycol is observed, which shows a decreasing tendency with the increase of molar fraction. A correlation for the <i>C</i><sub><i>p</i></sub> of the chosen DES and pure ethylene glycol is proposed for a better application of the data. molar fraction;DES;ethylene glycol;Deep Eutectic Solvent;Isobaric Molar Heat Capacities;C p;C p change;isobaric molar heat capacities 2020-01-09
