Abstract:

The computer models for T-x-y diagrams with the mono- and invariant monotectic equilibrium, and monovariant syntectic equilibrium by means of kinematical simulation of phase regions boundaries are considered. The effect of syntectic equilibrium changing for monotectic one is investigated with the material balances visualization.

Abstract:

Solid-liquid equilibrium in isomorphous amino acid systems has been investigated as a model for systems that form solid solutions. Solid- and liquid-phase compositions in L-valine + L-leucine, L-valine + L-isoleucine, and L-isoleucine + L-valine in water were measured over the entire range of solid composition, and it was shown (from mass balance and phase rule considerations) that these systems form solid solutions. The solid- phases resulting from isothermal and cooling crystallization experiments were also investigated using powder x-ray diffractometry which showed that homogeneous solid so

Abstract:

A fundamental step in the further developments of comprehensive modelling of the diffusive processes in liquids requires the possibility of obtaining reliable and accurate experimental data of the diffusion and thermodiffusion coefficients of multicomponent liquid systems. In the present work, we perform an experimental investigation of the diffusive properties of binary and ternary liquid systems. Two experimental techniques, the ‘Open Ended Capillary’ technique and the ‘Transient Interferometric Technique’ have been developed. Those techniques have been used for the experimental characteriza

The phase behaviour, rheological effects and interfacial properties of binary and ternary liquid mixtures have been studied near critical points.

Abstract:

The concept of a self-incompatible solvent is introduced as a molecule composed of two parts (compound 1 and 2) with unfavourable interactions. A third compound will be readily dissolved in this solvent to diminish this unfavourable interaction by dilution. The more incompatible compounds 1 and 2 are, the stronger this behaviour is expected to be. In this work, ionic liquids comprising non-polar carbon chain and polar ionic group are chosen to serve as a model of self-incompatible solvent. The interactions parameters k of the ionic liquids with active ingredients are investigated to examine th

Abstract:

Le calcul des diagrammes d'équilibre ternaires nécessite une bonne représentation analytique des grandeurs thermodynamiques d'excès des phases étendues. L’établissement de ces fonctions doit s'appuyer sur un nombre minimum, mais suffisant, d'informations expérimentales. Le formalisme quadratique de Darken, dans le cas des systèmes ternaires, permet de lisser les grandeurs d'excès dans les domaines des solutions moyennement diluées (xi 0,333). En divisant un système ternaire en trois quadrilatères adjacents, le formalisme de Darken nécessite 12 paramètres d'interaction binaires et seulement 3 p

The thermodynamic, crystallographic and many other physical and chemical properties of most of the species formed from this solution has been known for decades. However, there was no complete information or reliable data to confirm the existence of a unique double salt that is rich in sodium carbonate, up until five years ago when a research identified the double salt (~2Na ₂ CO ₃ • Na ₂ SO ₄) from the ternary system Na₂CO ₃Na₂SO ₄ H₂O.
