Deep Eutectic Solvents for Denitrification: Liquid-Liquid Equilibrium Data

Two deep eutectic solvents based on betaine and propylene glycol were prepared and their physico-chemical properties determined. Liquid-liquid equilibria at 298.15 K and atmospheric pressure were measured for 13 quasi-three-component systems involving hydrocarbons, pyridine, or thiophene. Marko Rogošić authored this study, which used NRTL and UNIQUAC models to describe the experimental phase diagrams.

Use Cases

• Modeling liquid-liquid phase equilibria based on experimental data for hydrocarbon-solute-DES systems.
• Comparing solvent performance for denitrification versus desulfurization based on calculated distribution ratios.
• Parameterizing thermodynamic models like NRTL and UNIQUAC for deep eutectic solvent systems.
• Screening potential deep eutectic solvent formulations for specific separation tasks.

Strengths

• Experimental data covers 13 distinct quasi-three-component systems.
• Phase equilibria determined at a controlled temperature of 298.15 K and atmospheric pressure.
• Results validated against two established thermodynamic models (NRTL and UNIQUAC).

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is limited to a single temperature and pressure condition.
