HPLC法测定2,3-二氰基-2,3-二苯基丁二酸二乙酯的热异构化反应动力学参数

Determination of Dynamic Parameters of Thermal Isomerization Reaction of meso Diethyl 2,3 dicyano 2,3 diphenylsuccinate by HPLC

采用ＨＰＬＣ法测定２，３－二氰基－２，３－二苯基丁二酸二乙酯的内消旋体在六种不同溶剂中和熔融情况下热异构化反应动力学参数（Ｋ，Ｋｏｂｓ，Ｅａ，△Ｇｏ，△Ｈ＝＼，△Ｓ＝＼），定量分析的相对误差和标准偏差分别小于±０６５％和０３５。

The dynamic parameters of thermal isomerization reaction of meso diethly 2,3 dicyano 2,3 diphenylsuccinate were determined by HPLC in six solvents and melt state,with a relative error and a standard deviation of less than ±0,65% and 0 35,respectively
