ABSTRACT
The mass diffusion coefficients of dimethyl carbonate in heptane and in air were measured at T ) (278.15 to 338.15) K under atmospheric pressure. The experiments were carried out using a digital holographic interferometry system that was constructed by our group. The mass diffusion coefficient of KCl in standard aqueous solution at a temperature of 298.15 K and condensation of 0.33 mol *L-1 was measured to verify the accuracy and reliability of the system. The experimental uncertainties in temperature and mass diffusion coefficient are estimated to be no greater than ( 0.16 K and ( 0.2 %, respectively.
