Hansen solubility parameters for supercritical water

► Dispersion, polarity, and hydrogen bonding Hansen solubility parameters of supercritical water (SCW) are presented. ► They pertain to the ranges relevant to applications of SCW: 400-700 °C and 25-100 MPa. ► The Hansen parameters are used to predict the solubilities of the bisphenol A polycarbonate and Nylon 66 in SCW.
