| Resumo | |
The aim of this study was to evaluate the formation of aqueous two-phase systems (ATPS) based on different protic ionic liquids (PIL), synthesized using amines, and organic or inorganic acid, and acetonitrile (ACN). The ATPSs are used to pre-purify genipin from genipap (Genipa americana L.). All PILs (purity above 98%) were able to form ATPSs with ACN, the size of the biphasic region being directly dependent on salting-out aptitude of PIL anions and relative hydrophilicity of the corresponding cations. The highest solid liquid extraction of genipin from genipap was achieved by using aqueous ACN solution at 75% (16.79 +/- 0.06 mg g(-1) dry raw material) as extractant. After the extraction stage, the ATPS was used as an integrated platform to pre-purify the genipin present in the extract. Three different overall mixture point compositions were tested, and those formed by {[}MEA]{[}H(2)Cit] (25 wt%) + ACN (45 wt%) + water (30 wt%) at 298.15 +/- 1.00 K and 0.10 +/- 0.01 MPa showed the highest selectivity (S = 4.202 +/- 0.009) and recovery of genipin in top phase (R-TG = 56.74 +/- 0.04%), and the purification factor in top phase was 5.9 fold.
