Abstract

The equilibrium solubility of poly(β-hydroxybutyrate) (PHB) in supercritical carbon dioxide was studied. The effects of the main parameters such as pressure, temperature, and solvent density on solubility were determined at temperatures ranging from (308 to 348) K and pressures from (122 to 355) bar. The measured solubility was correlated using the model proposed by Chrastil.
