摘要: Abstract Density, viscosity, surface tension and molar volume of propylene glycol + water mixtures at 293, 298, 303, 308, 313, 318, 323 K are reported, compared with the available literature data Jouyban–Acree model was used for mathematical correlation data. The mean relative deviation (MRD) as an error criterion MRD values density, different investigated temperatures 0.1 ± 0.1%, 7.6 ± 6.4%, 3.4 ± 3.7%, 0.4 ± 0.4%, respectively. corresponding MRDs predicted properties after training using experimental 298 K 0.1 ± 0.2%, 12.8 ± 9.3%, 4.7 ± 4.1% 0.6 ± 0.5%, respectively tension,
