“…The agreement of these data with the other primary sources was evidenced in Ref. [28]. The temperature range covered by the data has been extended with the data from Le Neindre and Garrabos [35].…”

“…A round robin project [27,28] was then conducted under the auspices of the International Union of Pure and Applied Chemistry (IUPAC) to investigate the discrepancies among the various data sets of transport properties of R134a. New series of experimental data have been obtained in that project and they are supposed to have an accuracy better than the previous measurements.…”

“…The current situation with the reported DES viscosity measurements that display large deviations between different research works is reminiscent of initial measurements on refrigerants in the late 1990s where unchecked water content also produced large differences in quoted viscosity values. 19 Furthermore, in order to develop reliable models, there is a need for viscosity data for varying HBA/HBD mole ratios. Currently, such data is available only for a limited number of DESs.…”

Viscosity of Choline Chloride-Based Deep Eutectic Solvents: Experiments and Modeling

et al. 2020

Deep eutectic solvents (DES) have emerged as promising 'green' solvents, but their successful industrial application requires relatively low viscosity. DES prepared from choline chloride and glycols offer such possibility. Viscosity and density are reported for a number of DES obtained by mixing choline chloride and a glycol (ethylene glycol, 1,2-propanediol, 1,3-propanediol, and 1,4-butanediol). The measurements were performed at 101.3 kPa, at temperatures between 293.15 K and 333.15 K, and for different mole ratios of the glycol and choline chloride. The viscosity was measured with a capillary viscometer, while the density was measured by means of a vibrating U-tube densimeter. The density and viscosity data have expanded relative uncertainties of 0.2% and 2.0%, respectively, with a coverage factor of 2. The viscosity of pure glycols was modeled using the extended hard-sphere (EHS) model that has its basis in kinetic theory and the molecular description of the fluid. Each DES was treated as a binary mixture, and the EHS model was used, with a mole average mixing rule, to calculate its viscosity. The measured DES viscosity data were represented with the average absolute deviation of 1.4% and a maximum deviation of 7%.

“…Most recently, and perhaps most unfortunately, the new range of environmental refrigerants fell victim to an inappropriate combination of instrument and working equation during the early measurement of the viscosity of some of the liquids. (4) Several major lessons have been learned. The use of a time-dependent method removes some of the difficulties of precise measurements arising from small perturbations from equilibrium.…”
