  • Transport properties (viscosities, thermal conductivities, ...)
  • Enthalpies (phase change, formation, ....)
  • Heat capacities
  • Surface tensions
  • and more
• Mixture properties
  • Vapor-liquid equilibria
  • Liquid-liquid equilibria (miscibility gaps)
  • Solid-liquid equilibria (solubilities)
  • Activity coefficient at infinite dilution
  • Gas solubilities
  • Azeotropic and zeotropic data
  • Heats of mixing
