“…The reaction solution is mainly composed of 27.2 %w in 1,3-diaminopropane, 3.7 %w in pyrazolidine, 5.7 %w NaCl, 0.1 %w NaOH and 63.3 %w water, the amine will thus control the phenomenon of phase separation by solvent effect. We determined three isothermal sections (289 K, 313 K and 323 K) of the solid-liquidliquid isobaric ternary system H 2 O-DAP-NaOH by ITA [3] (Isoplethic Thermal Analysis) and acid-base titration.…”

“…This is the reason why we have chosen a method of the isoplethic type [6], fitting well with the multiconstituted and polyphased systems and without needing systematic chemical analyses. By definition, these methods consist to linearly modify the global composition of a mixture, at constant pressure and temperature, and to follow the evolution of an intensive physical property (conductivity [7], pH, density [8] …) of the monophased solution or of the liquid phase in equilibrium with one or more solid phases.…”

Potassium borohydride KBH4 is an attractive chemical hydride for H2 generation and storage in portable fuel cell applications. Nevertheless, the control of the by-products, in terms of stability and solubility in aqueous solutions, is one of the limiting steps of the hydrolysis reaction of H2 release. We report here some physicochemical properties of concentrated KBO2 aqueous solutions: solubility and gravimetric density are measured as function of temperature between 10 to 80°C. The stability of hydrated metaborates KBO2.xH2O solid phases (with x = 4/3 and 4) in alkaline aqueous solutions is also evaluated at 20°C.

Abstract. The development of the Discontinuous lsoperibolic Thermal Analysis (AITA) aims at setting up a new phase diagram investigation technique efficient in the case of organic component systems. A heterogeneous system (with at least one liquid phase) is kept in isoperibolic conditions and submitted to discontinuous composition shifts by successive additions of a thermostated solvent (or solution). It results in perturbations of the equilibrium state and then physical phenomena which bring the system back to the equilibrium. The phenomena resulting fkom the addition of liquid (dissolution, dilution.. .) imply enthalpy changes which cause temperature variations of the system. An adapted exploitation of the temperature versus time signals leads to the determination of the topology of the corresponding phase diagram.
