WebThe table below gives thermodynamic data of liquid CO 2 in equilibrium with its vapor at various temperatures. Heat content data, heat of vaporization, and entropy values are relative to the liquid state at 0 °C temperature and 3483 kPa pressure. To convert heat values to joules per mole values, multiply by 44.095 g/mol. WebFig. 1 Concept of biphasic photocatalysis using hydrophobized PHI. KPHI is synthesized by ionothermal treatment of melon in KSCN melt. The treatment leads to a partial exchange of surface NH 2-groups for ionic C N − functions, thus reducing H-bonding in the polymer and allowing for the preparation of colloidally stable dispersions of small KPHI particles.
