烷基多苷反应中的非均相与均相动力学模型

Kinetic Models of the Synthesis Alkyl Polyglycosides in Heterogeneous Reaction and Homogeneous Reaction

用二步法研究了合成十二烷基多苷动力学 ,建立了以化学反应为控制阶段条件下的动力学模型并确定了其参数。通过验证 ,实验值与计算值基本吻合。丁基多苷和十二烷基多苷的实验值与计算值平均误差分别小于 2 .4%和 4.0 %

The kinetics of the synthesis of dodecyl polyglycosides is presented in two steps.The kinetic models are established under the condition of taking chemical reaction as the control step,and kinetic parameters of the models have been estimated.The experimental results are well consistent with what are predicted by these models,with the mean errors of experimental value and calculation value for concentrations of butyl polyglycosides and dodecyl polyglycosides being less than 2.4% and 4.0% respectively.
