Resumo: | Herein, the influence of HV (hydroxyvalerate) addition (8.0 and 8.7 wt% HV) on the PHBV (poly(3-hydroxybutyrate-co-3-hydroxyvalerate)) composition from the perspective of phase equilibrium in high-pressure {(CO2 (1) + chloroform (2) + [PHBV - 8.0 wt%] (3) and (CO2 (1) + chloroform (2) + [PHBV - 8.7 wt%] (3)} systems was examined using the static synthetic method with a visual variable-volume view cell at temperatures ranging from 303.15 to 333.15 K, pressures approximately 10 MPa, and different concentrations of PHBV (HV = 8.0 and 8.7 wt%) in chloroform (0.01 and 0.02 g.cm−3). Transitions of the solid-vapor-liquid (SVL) were observed. The experimentally determined phase transitions were successfully modeled using the PC-SAFT equation of state. |
