Gaseous p–v–T Property Measurements for Titanium Tetrachloride from 873.0 to 1173.0 K and Low Pressure of 34.05 kPa

[Image: see text] For exploring the chemical reaction mechanism and the heat and the mass transfer of the TiCl(4)–Mg system in the Kroll process, it is of fundamental and practical importance to determine the gaseous p–v–T property for titanium tetrachloride at supercritical temperature and low pressure. The p–T–x data for the xTiCl(4) + (1 – x) Ar binary gas system are measured and presented in this study. Based on the Peng–Robinson (P–R) equation of state (EoS) of argon at temperatures from 873.0 to 1173.0 K, the gaseous p–v–T property of titanium tetrachloride has been estimated, and a new three-term truncated virial EoS for titanium tetrachloride is developed along 10 isotherms and 8 isodensities.
