The　saturated　vapor　pressures　of　a　series　of　α-pinene　derivatives　including　camphene,　isobornyl　acetate,　(±)-limonene,　dihydromyrcenol,　pinane,　and　dihydromyrcene　were　determined　at　the　pressure　ranging　from　(0.8　to　50.0)　kPa　by　the　boiling　point　method.　Good　agreement　of　the　correlated　values　was　obtained　when　the　experimental　data　of　vapor　pressure　and　temperature　were　correlated　by　the　Antoine　equation,　and　the　parameters　A,　B,　and　C　were　estimated.　The　molar　enthalpies　of　vaporization　ΔvapH　m　of　these　compounds　were　estimated　within　the　experimental　temperature　range　by　the　Clausius-Clapeyron　equation.　Furthermore,　the　reliability　of　regressed　parameters　obtained　from　the　Antoine　equation　in　the　range　of　experimental　data　was　verified.　©　2014　American　Chemical　Society.
