摘要
本文研究了紫苏色素在不同ｐＨ条件下热降解的动力学过程．结果表明，紫苏色素在ｐＨ＝３－７．５的范围内，其热降解反应为一级反应．经计算机拟合得到不同ｐＨ条件下其热降解反应的动力学方程和反应活化能。
The kinetics of the thermo degradation reaction of Perilla Color were studied. The results showed that the thermo degradation reaction is first order reaction, and the reaction rate was influnced by temperature and pH value. The apparent rate constants and activation energies of the thermo degradation reactions at different conditions were calculated.
