摘要
采用基团贡献法对三羟甲基丙烷和正辛酸反应合成三羟甲基丙烷三辛酸酯进行了热力学计算与分析,得到了反应摩尔焓变、摩尔Gibbs自由能变与温度的关系。分析结果表明,反应吸热,不能自发进行。
Thermodynamic analysis for the synthesis of trimethylolpropane tricaprylate from trimethylolpropane and n- octanoic acid was conducted by group- contribution method.The relationships between the molar enthalpy changes of the reaction and molar Gibbs free energy changes with temperature were established.The results showed that the reaction can not take place spontaneously,and it is endothermic.
