摘要
对现行工艺条件下水相悬浮法氯化反应,采用经验式y=10.391 lnx+21.602预测氯化反应程度,即根据氯化反应时间(x)计算氯质量分数(y),相关系数R2=0.985 4;利用方程式Y=0.061 9e0.042 8X,用实际所测得的氯质量分数(X),计算出氯化反应相应的转化率(Y),相关系数R2=0.997 2;水相悬浮法氯化工艺条件下的表观反应级数为:n=0.95;经过恒定反应时间,对不同反应温度对氯含量的影响进行考察,计算出氯化反应的表观活化能为13.36 kJ/mol。
The chlorination kinetics of TPI in aqueous suspension was studied by the methods of chemical analysis and regression analysis.The results showed that the chlorination degree(y)could be predicted from the chlorination time(x),with the empirical formulation y=10.391ln(x)+21.602(R^2=0.9854),and the chlorination conversion(Y) can be obtained from the observed chlorine content(X) with another formulation Y=0.0619e^(0.0428X)(R^2=0.9972).The apparent reaction order of the chlorination reaction of TPI in aqueous suspension process was found to be n=0.95.With a certain reaction time and different reaction temperature,we could get the apparent activation energy of the chlorination reaction of TPI aqueous suspension:Ea=13.36kJ/mol.
