摘要：

New absolute measurements of the viscosity of n-decane and binary mixtures of n-heptane with n-decane are presented. The measurements, performed in a vibrating-wire instrument, cover a temperature range 290-330 K and pressures up to 70 MPa. The concentrations studied are 40 and 70% by weight of n-heptane. The overall uncertainty in the reported viscosity data is estimated to be +/- 0.5%. The present measurements together with other n-heptane+n-alkane viscosity and thermal conductivity measurements, are used to develop a consistent semiempirical scheme for the correlation and prediction of these mixture properties from those of the pure components.
