The results show that the DSC curve for the initial 50% of conversion degree of NC can be de-scribed by the first order autocatalytic equation dy/dt=-10^(16.3)exp(-181860/RT)y-10^(16.7)exp(-173050/RT)y(1-y) and that for the latter 50% conversiondegree of NC described by the reaction equations dy/dt=-10^(16.4)exp(-154820/RT)y(n=1) and dy/dt=-10^(16.9)exp(-155270/RT)y^(2.80)(n≠1).展开更多
