The self-diffusion coefficients, densities, and shear viscosities of liquid 2-ethylhexyl cyclohexanecarboxylate (EHC) were measured as a function of pressure from 1 to 4500 bar within the temperature range from-20 to 80'C. The Stokes-Einstein equation is applicable over 5 order of magnitude changes in self-diffusion and viscosity. The experimental data obtained are compared to those for the complex liquid of 2-ethylhexyl benzoate (EHB) in ...
