摘要
提出T_(?)、T_m、T_c、p_c和V_c5种基础物性的三基团参数关联式,拟合了相应的基团参数值,对上述各物性估算的平均偏差分别为1.35%、8.01%、0.68%、2.73%和1.44%,准确度高于目前文献推荐的Joback法.
A three group parameters correlation of physical properties Tb,Tm,Tc, pc and Vc is proposed, and the numerical values of relative group parameters are presented. The average percentage deviations of estimation are 1.35, 8.01, 0.68, 2.73 and 1.44 respectively, which show higher accuracy of the present method than that of the Joback method recommended in literature.
