The evaporation of LaCl3, LaBr3 and Lal3 was investigated in closed tubes under argon atmosphere and correlated with data in the literature. The enthalpies and entropies of evaporation were derived from the temperature functions of pressure:

ΔH°(v, LaCl3, T) = 48,5 ± 2 kcal/mol, ΔS°(v, LaCl3, T) = 22,0 ± 3 cal/K-mol

ΔH°(v, LaBr3, T) = 48,0 ± 2 kcal/mol, ΔS°(v, LaBr3, T) = 24,0 ± 2 cal/K-mol

ΔH° (v , Lal3, T) = 49,5 ± 2 kcal/mol, ΔS°(v, Lal3,T) = 29,0 ± 2 cal/K-mol
