摘要

Densities and viscosities of methanol + dimethyl methylphosphonate and methanol + dimethyl phosphite binary mixtures were measured over a temperature range of (293.15 to 333.15) K at atmospheric pressure. The experimental data were compared with literature values. From these data, excess molar volumes (V (E)) were calculated. The density data were fitted to a second-order polynomial, and the viscosity data were fitted to the Andrade equation.
