摘要
利用Benson基团贡献法计算了四氯乙烷脱氯化氢制三氯乙烯反应中部分物质的热力学函数熵Sθ、热容Cp、Gibbs自由能及反应的焓变ΔrHθm、熵变ΔrSθm、Gibbs自由能变ΔrGθm、反应平衡常数Kp及四氯乙烷的平衡转化率.结果表明,反应温度高于460 K时,四氯乙烷脱氯化氢制三氯乙烯反应在热力学上是可行的.
The standard entropy Sθ,heat capacity Cp,Gibbs free energy,and the change of enthalpy ΔrHθm,entropy ΔrSθm and ΔrGθm,equilibrium constant Kp and equilibrium conversion of the reaction of some compounds related to dehydrochlorination of tetrachloroethane to trichloroethene were calculated by the method of Benson group contribution.The results show that the reaction is thermodynamically feasible when reaction temperature is higher than 460 K.
