%X Based on the method of ε-NTU, a mathematical modeling of ester-interchange reaction for dimethyl terephthalate (DMT) with ethylene glycol (EG) by acetate system was simulated, and, in addition, the corresponding kinetic equation is obtained by using the theoretical method of simulation. That is,-(dc)/(dt)=kc(c+k')where:-(dc)/(dt)= the reaction rate of the monomer, C -concentration of the monomer, θ-Suitable parameterk,k'-constant (k'=θ/k)The experimental results have showed that the ester-interchange reaction is a reaction neither first order or second order nor third order,but it is a reaction of secondary linear type. Yamanis2] doubted the correctness of the method that has been proved.Moreover,we have suggested the physical meaning of parameters.
