Abstract

The time course of the glucose isomerization was investigated. At equilibrium the fructose content in the reaction mixture was 52% of the initial glucose concentration. The equilibrium constants K1 and K-1 for the isomerization reaction were determined at 60 degrees C. Two graphical plots were developed to reduce the problems of determining the individual constant. These plot methods for chemical reaction kinetics were applied with equal validity to the kinetics of glucose isomerization process.

摘要

研究了葡萄糖异构化的时间进程。在平衡时,反应混合物中的果糖含量为初始葡萄糖浓度的52%。在60℃下测定了异构化反应的平衡常数K1和K-1。开发了两种图解法以减少确定单个常数的问题。这些化学反应动力学的绘图方法同样有效地应用于葡萄糖异构化过程的动力学。
