摘　　要：用Benson基团加和法估算了有机物的Δ_(f)H_(m)^(θ)(g,298.15K)及S_(m)^(θ)(g,298.15 K)。用Rihani基团加和法估算了有机物的C_(p,m)(g)与T的关系。用Fedors基团参数法估算了液态有机物的Δ_(v)H_(m)^(θ)(l,298.15 K)。用Joback法估算了液态有机物的正常沸点。通过转换得有机物的Δ_(f)H_(m)^(θ)(l,298.15 K)及S_(m)^(θ)(l,298.15 K)。由估算的热力学数据导出了各步反应的Δ_(r)H_(m)^(θ)、Δ_(r)S_(m)^(θ)、Δ_(r)G_(m)^(θ)、K^(θ)分别与T之间的关系,并对这些关系式进行了讨论。The Δ_(f)H_(m)^(θ)(g,298.15K)and S_(m)^(θ)(g,298.15K)of organic compounds were estimated by the Benson group summation method.The relationship between Cp,m(g)and T of organic matter was estimated by the Rihani group addition method.The Δ_(v)H_(m)^(θ)(1,298.15K)of liquid organics are estimated by the Fedors group parameter method.The Joback method is used to estimate the normal boiling point of liquid organics.The Δ_(f)H_(m)^(θ)(1,298.15 K)and S_(m)^(θ)(1,298.15 K)of organic matter are obtained by conversion.The relationship between Δ_(r)H_(m)^(θ),Δ_(r)S_(m)^(θ),Δ_(r)G_(m)^(θ),K^(θ) and T of each step of the reaction was derived from the estimated thermodynamic data,and these relationships were discussed.
