Table 4 reports the partition coefficients and costs for several organic solvents with respect to BTX compounds. As suggested by Collins & Daugulis (1999), Adol 85 NF solvent realizes a good trade-off between cost, biocompatibility and selectivity, therefore we adopted it in the process simulation as partitioning phase in the TPPB reactor.
