Abstract A group topologic space method for estimating enthalpies of vaporization at normal boiling points for organic compounds has been proposed.Expression for estimating enthalpy of vaporization at boiling point has been proposed,with the numerical values of relative group parameters presented.The average percent deviation of estimation of the enthalpy of vaporization at boiling points is 1.052,comparing with the common used methods,our proposed method shows high accuracy and reliability.
