主 题:Rare earths PrCl 3 AlCl 3 Vapour complex Quenching Thermodynamics
摘 要:Thermodynamic study on the reaction PrCl 3(s) +( x /2) Al 2Cl 6(g) =PrAl x Cl 3 x +3(g) was carried out by quenching experiments within 604~827 K and 0 05~0 15 MPa. The results suggested that the PrAl 3Cl 12(g) complex was the predominant species. The equilibrium constants of the reaction were measured. The reaction enthalpy and entropy derived from the measurements were ΔH 0 298 =(38 2±2) kJ·mol -1 and ΔS 0 298 =(1 2±3) J·mol -1 ·K -1 .
