摘要：

The dynamic viscosity and density of the n-heptane + nonylbenzene binary mixture have been measured as a function of concentration, between 1 and 400 bar at temperatures 40, 60 and 80-degrees-C. The 105 experimental values were adjusted by means of the Bloomfield and Dewan relationship and Flory's theory, without employing any additional adjustable parameters. The mean deviation observed is 5.7%. This shows that the range of applicability of this representation, tested successfully at atmospheric pressure, can be extended to conditions of higher pressure. For comparison, the experimental results have been tested against other laws, representative of the viscosity of mixtures, relying upon an adjustable empirical parameter.
