High-pressure viscosity and density of n-alkanes
- Univ. of Maine, Orono (United States)
High-pressure viscosities and densities of n-butane, n-pentane, n-hexane, and n-octane have been measured with a specially designed falling cylinder viscometer. Data cover the pressure range from 10 to 70 MPa at temperatures from 310 to 450 K. When the viscosity is plotted as a function of density, the data at all temperatures and pressures are shown to reduce to a single curve for each alkane. An exponential relationship of the form [eta] = B[sub 1] [times] exp(B[sub 2] [times] [rho]) + B[sub 3] is used to describe the density dependence of viscosity. The logarithmic viscosity of the alkanes changes linearly with the inverse temperature at all pressures. The density shows a linear dependence on temperature. 33 refs., 18 figs., 10 tabs.
