Abstract: This work presents densities, dynamic viscosities, surface tensions, and refractive indices of three methyl ethereal solvents: cyclopentyl methyl ether (CPME), tert-amyl methyl ether (TAME), and tert-butyl methyl ether (MTBE). CPME and TAME were chosen as methyl alternatives of the common but environmentally problematic MTBE. The highest density, viscosity, surface tension, and refractive index were observed for CPME and the lowest for MTBE. The results are in good agreement with other authors’ data. Based on the experiments, the critical temperature and the critical pressure of CPME were estimated. The parachor, molar refraction, and critical compressibility factor were calculated from experimental data. Parameterisations of the experimental data using corresponding correlative models are presented.

Keywords: CPME ; TAME ; Density ; Viscosity ; Surface tension ; Refractive index
