摘要：

The standard enthalpies of formation of KMgH2F and K2MgF4 were determined by reaction with hydrochloric acid solutions (0.5 M HC1 and 3 M HC1 respectively). The standard enthalpies of formation of KMgF3, KMgHF2 and KMgH3 were estimated on the basis of the following measurements. ΔfHXXX(K2MgF4,cr,298K) = -2317 ± 20kJmol-1 ΔfHXXX(KMgF3,cr,298K) = -1727 ± 15kJmol-1 ΔfHXXX(KMgHF2,cr,298K) = -1246.5 ± 5kJmol-1 ΔfHXXX(KMgH2F,cr,298K) = -762.6 ± 10kJmol-1 ΔfHXXX(KMgH3,cr,298K) = -278.4 ± 5kJmol-1. © 1990.
