Density, viscosity, and speed of sound of carbitol + ۲-propanol + water mixtures at various temperatures: Measurement and mathematical modeling

Physicochemical properties data of solvent mixtures is an integral part of ‎designing new industrial processes, developing theoretical models and etc. In this work, physicochemical properties of ternary mixtures of carbitol with water and ۲-propanol including density, viscosity, and speed of sound in the entire range of compositions and temperatures including ۲۹۸.۱۵, ۳۰۳.۱۵, ۳۰۸.۱۵, and ۳۱۳.۱۵ K and atmospheric pressure of ۰.۸۶۸ MPa were carried out and compared with the available literature data. Jouyban–Acree and the Jouyban-Acree-van’t Hoff models were used for mathematical correlation of the obtained records. The mean relative deviation (MRD%) was used as an error scale. The related MRDs% for the predicted properties after training the Jouyban-Acree model were ۰.۲%, ۵.۹%, and ۰.۳%, and the Jouyban-Acree-van’t Hoff model were ۰.۲%, ۶.۰%, and ۰.۳% for density, viscosity, and speed of sound, respectively.
