Pressure-volume-temperature (PVT) property data at elevated temperatures and pressures play an important role in a variety of chemical processes and provide a fundamental database for the development and examination of thermodynamic models. This article describes a detailed experimental procedure of the floating-piston technique for determining PVT properties of pure liquids and polymer solutions in a wide range of temperatures and pressures. Some representative results using this technique are also given in this article, which agree with available literature data with a percent deviation within +/- 0.4%.
