Abstract  

Discontinuous isoperibolic thermal analysis (ΔITA) is a phase diagram investigation technique applicable to organic components systems (with at least one liquid phase). The elementary signal is composed by the evolution of the temperature of the system vs. time after a composition shift. A theoretical analysis and a mathematical modeling of this signal show that the overall enthalpy exchanged multiplied by a proportional factor can be obtained. From different experiments, evidence is given that this semi-quantitative calorimetric measurement is reliable. Thus, ΔITA allows consistent and accurate descriptions of phase diagrams and is a real relative calorimetric measurement technique.
