The standard ( p °=0.1 MPa) molar enthalpies of formation of crystalline 1,1,1-trifluoro-4-(2-thienyl)-4-hydroxy-3-buten-2-one, HTTFA, and 1,1,1-trifluoro-4-(2-thienyl)-4-mercapto-3-buten-2-one, HTTFAS, at T =298.15 K were measured by rotating-bomb calorimetry and the ...
Making use of the heat capacities thus estimated for La2Te3O9(s), and La2Te4O11(s), and the values of the heat of reactions leading to the two compounds obtained by Gospodinov [2] the respective standard enthalpies of formation at 298.15 K were found to be À2790.6 kJ molÀ1 and...
摘要: The standard enthalpies of formation of cerium alloys, Ce+Me (Me=Ru, Rh, Pd, Ir, Pt) and of lutetium alloys, Lu+Me (Me=Rh, Pd, Ir, Pt) were determined by direct synthesis calorimetry at 147±2 K. The following values of Δ...
