摘要
在间歇反应器内,对乳酸乙酯在353～368K下水解生成乳酸的反应动力学进行了研究,采用最小二乘法回归模型参数,得到乳酸乙酯水解反应速率方程。对模型显著性进行残差检验、F检验和Arrhenius检验。结果表明建立的动力学模型残差分布合理,参数回归显著,模型能较好地表达反应特性。
The reaction kinetics model for hydrolysis of the ethyl lactate into lactic acid at the temperature of 368 -353K had been investigated in the batch reactor experimentally with least squares method to be employed to regress the parameters of the equation. The significance of the model was tested by residual test, F test and Arrhenius test. The results showed that the residual of the model distributes reasonably and the parameters are regressed significantly. The model can express the characteristics of the reaction.
