Description

Total equilibrium vapour pressure, sublimation and vaporization enthalpies of scandium b-diketonate, Sc(C5H8O2)3(cr) and Sc(C11H19O2)3(cr) were measured in the temperature range 375 to 445 K and 365 to 455 by adapting a horizontal dual arm single furnace thermal analyzer as a transpiration apparatus, and their temperature dependence were found to fit the following equations: Sc(acac)-3, log pc/Pa 16.1391(±0.110) - 5437(±44)K/T, Sc(tmhd)3(cr) log pc/Pa 15.8201(±0.172) - 5272(±67)K/T and Sc(tmhd)3(liq), log pc/Pa 13.0788(±0.272) - 4222(±119)K/T. The sublimation and vaporization enthalpies of each scandium b-diketonates are calculated by using Clausius - Clapeyron equation. (author)
