Gas phase PVT properties and second virial coefficients of dimethyl ether

Experimental Measurement and Modeling of the Viscosity of Dimethyl Ether

“…The thermophysical properties of dimethyl ether are essential in practically designing unit operations, and many researchers have measured its properties. In recent years, the authors' group has launched a systematic study on the thermophysical properties of dimethyl ether, including vapor pressure, critical properties, pvT properties, surface tension, viscosity, thermal conductivity, and so on. − …”

Measurements of Gaseous Pressure-Volume-Temperature Properties for Ethyl Fluoride

“…The Burnett isochoric method adopted in this study was similar to that in the literature. 18 A schematic diagram of the experimental system for gaseous PVT properties is shown in Figure 1. The process is as follows.…”

“…By applying this method, gaseous PVT properties can be acquired in a wide temperature range with high precision. The Burnett isochoric method adopted in this study was similar to that in the literature . A schematic diagram of the experimental system for gaseous PVT properties is shown in Figure .…”

CHAPTER 1. Volumetric Properties: Introduction, Concepts and Selected Applications

“…86,[179][180][181] For molecular gases it is not possible to write Equation (1.11) as a Laplace transform, that is a formal inversion procedure does not exist in this case. The majority of virial coefficient data has been obtained by PVT (or PrT) measurements, [182][183][184][185][186][187][188][189][190][191][192][193][194][195][196][197][198] of which the Burnett technique 182-188 is perhaps the most commonly used. For subcritical temperatures, adsorption is a major problem, which has been, however, successfully resolved by Wagner and collaborators [191][192][193][194][195] by introducing a new compensation method based on Archimedes' buoyancy principle: two sinkers of identical mass and surface area but significantly different volumes were used.…”
