摘　　要：　用Benson基团加和法估算了蓖麻醇酸及其各反应产物的标准生成焓ΔfHΦm(298,g)、标准熵SΦm(298,g),用Rihani基团加和法估算了这些物质的理想气体热容CΦp,m(T)与温度的关系,分别导出了蓖麻醇酸各反应的标准焓变ΔrHΦm(T)、标准熵变ΔrSΦm(T)、标准吉布斯自由能变化ΔrGΦm(T)、标准平衡常数KΦp(T)与温度之间的关系.导出的结果可用于分析、控制和优化蓖麻醇酸各化学反应及其工艺过程.By the benson rule of group additivity, standard formation enthalpy \%Δ\%\-f\%H\%\+Φ\-m(298,g) and standard entropy \%S\%\+Φ\-m(298,g) of ricinoleic acid and its reaction products were estimated, and by the Rihani rule of group additivity, the relation between heat capacity for an ideal gas \%C\%\+Φ\-\{p,m\}(\%T\%) of each above substance and the temperature was estimated. The relations between standard enthalpy change \%Δ\%\-r\%H\%\+Φ\-m(\%T\%), standard entropy change \%Δ\%\-r\%S\%\+Φ\-m(\%T\%), standard Gibbs free energy change \%Δ\%\-r\%G\%\+Φ\-m(\%T\%) and standard equilibrium constant \%K\%\+Φ\-p(\%T\%) of various ricinoleic acid reactions and the temperature were respectively deduced. The deduced results can be used to analyze, control and optimize chemical reactions and chemical processes of ricinoleic acid.
