摘要：

The total vapour pressures of iron diiodide were measured by the torsion-effusion method and the temperature dependence is represented by the following equation: log {p(kPa)} = (10.80 +/- 0.40) - (9860 +/-300)/T The standard sublimation enthalpy of the reaction: FeI2(s) --> FeI2(g), Delta(r)H(0)(298) = 194 +/- 2 kJ mol(-1), was obtained from second- and third-law treatments of the pressure data considering the partial pressure of FeI2(g) equal to 0.70 p(tot). Comparisons with previous results are made.
