dc.description.resumo | The present work investigated the SS performance with focus on the addition of second collecting phase to intensify the separation of vanillin and eugenol. First, experiments were performed with only n-octanol as the only collecting phase and the effects of solutes concentration and pH of the bottom phase were evaluated on the separation efficiency (E%). Then,the SS process was performed in a three-liquid-phase system formed by n-octanol/PEG 400/(NH4)2SO4 and the results were evaluated based on E%, distribution coefficient (D) and vanillin selectivity (RVAN/EUG) values. When compared to single component experiments, the presence of another solute had little effect on the E% values of vanillin and eugenol, regardless of the range of the initial concentration. Moreover, in SS with n-octanol/acetate buffer it was possible to reach the highest values of E% for vanillin (53.83%) and eugenol (85.37%) in experiments with pH equal to 4.5. On the other hand, the three-liquid-phase system achieved selectivity at least twice as high as two-liquid-phase systems and D values higher than 25 for vanillin in the PEG 400-rich phase. Thus, SS using three-liquid-phase system appears as an alternative to solve multicomponent separation problems involving bioactive compounds | pt_BR |
