Kinetic Study on the Preparation of Sweet Potato Starch Phosphoric Esters

中文摘要英文摘要

研究制备甘薯淀粉磷酸酯的反应动力学过程,建立三偏磷酸钠浓度与反应温度、反应时间之间的动力学模型:cA=c0e-1.18×1013×e-1.12×104×1/T×t。结果表明:该模型预测值与实测值吻合良好。

The reaction kinetics for the preparation of sweet potato starch phosphoric esters was investigated in this study.A kinetic model that describes sodium trimetaphosphate concentration(cA) against reaction time(t) and temperature(T) was obtained as follows:cA=c0e-1.18×1013×e-1.12×104×1/T×t,where c0 was initial sodium trimetaphosphate concentration.The predicted values from the model were in good agreement with the experimental values.
