Ternary and binary LLE measurements for solvent (2-methyltetrahydrofuran and cyclopentyl methyl ether) + furfural + water between 298 and 343 K

- Novel LLE of 2-methyltetrahydrofuran or cyclopentyl methyl ether + furfural + water.
- High performance solvents for liquid-liquid extraction exhibited.
- Modelled with UNIQUAC-HOC activity coefficient model.
- Comparison to other industrial solvents with distribution coefficient and selectivity.

The suitability of two solvents for the extraction of furfural from aqueous streams is assessed through novel ternary and binary liquid-liquid equilibria data for mixtures of solvent (2-methyltetrahydrofuran or cyclopentyl methyl ether) + furfural + water. The measured data are reported along with regressed binary interaction parameters for UNIQUAC-HOC activity coefficient model and further analyzed through distribution coefficients and selectivity for furfural. Out of the two solvents, cyclopentyl methyl ether presents a very high selectivity along with good distribution coefficient in the entire temperature range.
