Abstract

The distribution coefficients and selectivities required for extraction
purposes were predicted with a thermodynamic equation of state for the
ternary system formic acid/water/extraction solvent. These predictions
were validated with experimental data from the literature and
experimental data from the oxidation of biomass to formic acid process
measured in this work. Extraction solvents discussed in this work are
1-butanol, 1-pentanol, 1-hexanol, 1-heptanol, 1-octanol, 1-decanol,
ethyl n-butyl ether, diisopropyl ether, di-n-butyl ether,
benzyl formate, and heptyl formate. The considered temperature ranged
from 273 to 363 K under atmospheric pressure. Perturbed-chain
statistical associating fluid theory (PC-SAFT) was used for prediction
purposes applying an approach as simple as possible and as complex as
necessary to achieve trustworthy data for selecting the best extraction
solvent. Using PC-SAFT allowed identifying 1-hexanol as the most
promising solvent out of the 11 extraction agents. The predicted data
were in good agreement with the experimental distribution coefficients
and the selectivities, which are very sensitive to experimental
uncertainties.
