In this paper, we study the universal behavior of the temperature-dependent vaporization enthalpy in equilibrium vapor–liquid phase transitions of simple fluids. We find that, under some reduction using critical data, the experimental curves of vaporization enthalpy versus the saturated temperature will overlap with each other, i.e. the universal behavior experimentally holds for the temperature-dependent vaporization enthalpy, in the temperature range from the triple point to the critical point, for simple fluids. An empirical correlation describing this universal behavior is proposed and compared with reference data and other correlations. Different from others, our correlation only needs the critical temperature as input parameters.

The effect of gamma pre-irradiation of the mixed nickel-magnesium oxide catalyst on the kinetics of hydrogenation of maleic acid in the liquid phase has been studied. The changes of the hydrogenation rate are compared with the changes of the adsorbed amount of the acid and with the changes of the solution composition, activation energy, and absorbed dose of the ionizing radiation. From this comparison and from the interpretation of the experimental data it can be deduced that two types of centers can be distinguished on the surface of the catalyst under study, namely the sorption centres for the acid and hydrogen and the reaction centres.
