The　solubility　of　borneol,　camphor,　and　isoborneol　in　four　solvents　(i.e.,　acetone,　ethanol,　p-cymene,　and　p-xylene)　was　measured　by　the　static　equilibrium　method　within　the　temperature　range　of　296.65-348.85　K　under　the　atmosphere.　The　fusion　points　and　fusion　enthalpies　of　borneol　and　isoborneol　were　determined　by　differential　scanning　calorimetry.　The　Apelblat　equation,　Wilson　model,　and　NRTL　model　were　employed　to　correlate　the　measured　solubility　data,　and　the　NRTL　model　fits　the　measured　data　better.　Mixing　properties　of　each　solute-solvent　pair　are　calculated　by　the　NRTL　model.
