Abstract This article is the second of three projected IUPAC Technical Reports on reference materials for phase equilibrium studies. The goal this project was to select systems with critically evaluated property values verification instruments and techniques used in studies mixtures. report proposes seven solid–liquid studies, covering four most common categories binary mixtures: aqueous organi...

The binary MgO–ZnO and CaO–ZnO systems the ternary CaO–MgO–ZnO system were thermodynamically optimized with phase equilibria studies in this study. Bragg-Williams random mixing model was used for solid solutions, while Modified Quasichemical Model liquid solution. thermodynamic optimization conducted using Factsage 8.1 thermochemical software. diagrams fit well experimental results. performed a...

Abstract UO 2 (NO 3 ) and UF 4 are significant intermediates that connect different chemical unit operations (such as dissolution, evaporation, concentration, extraction etc.) in uranium industry. Commonly, there is a basic physicochemical question about phase equilibrium of ternary systems + HNO H O HF O, it crucial to understand the behavior thermodynamic properties them with continuous devel...

This work focuses on the experimental measurement and modeling of solid–liquid equilibria containing continuous binary solid solutions crystallized from solvent mixtures for usage in antisolvent crystallization. The newly constructed quaternary phase diagrams l-valine/l-leucine water/2-propanol water/acetone systems are analyzed compared to those water/ethanol mixtures. Experimental data sets d...

Available literature on the thermodynamic properties of binary CoSO4 – H2O system has been reviewed and used to derive a model for calculating solution phase equilibria in thermodynamically consistent manner. The is based Pitzer ion interaction approach and, with 10 adjustable parameters, able reproduce available data good accuracy from 270 374 K. length exact form temperature dependence was op...

Solid precipitation from aqueous formaldehyde solutions is a major technical problem, leading to troubles such as plugging and fouling. While these problems are ubiquitous in technology, it hard predict them, so their mitigation difficult. Data on the formation of solid phase formaldehyde-containing systems scarce basically only available for system (formaldehyde + water); even few data contrad...

Abstract In cryogenic liquefaction processes, CO 2 poses a solid‐formation risk even in trace concentrations. We present solid–fluid equilibrium (SFE) data for liquid methane at concentrations from (52 to 500) ppm, extending the available and indicating that models tuned existing over predict solubility of LNG storage temperatures (~112 K) by nearly factor 3. The new are used improve SFE model ...

This work considers the equilibria between stable phases of Cr–Cu–O ternary chemical system at atmospheric pressure and in a large temperature range that includes high-temperature liquid phase. Based on thorough evaluation literature data, we performed complementary experimental investigations solid-phase properties (especially mixed oxides) by implementation spark plasma sintering microanalysi...
