    The kinetics of PTT direct esterification under different temperature was studied. The kinetics model of direct esterification was obtained through treatment of zero order and first order kinetics model respectively. Experimental data showed that the first order model fitted the reaction more.

    Abstract The cure kinetics of a phenylethynyl‐terminated poly(etherimide) are examined via differential scanning calorimetry (DSC) measurements. Isothermal holds at temperatures ranging from 325°C to 360°C provided the necessary information to develop reaction kinetics models using both first‐order reaction kinetics and combination reaction kinetics. The first‐order reaction kinetics model works well for quick estimates of degree of cure versus time over the experimental temperature range. However, significantly more accurate predictions of degree of cure versus time were provided by the combination reaction kinetics model. The lack of accuracy in the first order model is due to the fact that the reaction cannot be described by a simple order. The experimental procedures followed to obtain the cure kinetics data and the construction of the models from this data are described; the predictions of these models are compared with the experimental results.

    A reduced chemical kinetics including 20 species and 16 global reactions was obtained by reducing the detailed kinetics for ethylene combustion with the method of quasi-steady state approximation(QSSA).Experimental measurements of a laminar premixed ethylene/O2/Ar flame were carried out on the combustion station at National Synchrotron Radiation Laboratory(NSRL) to validate the kinetics.One-dimensional numerical method was implemented to simulate the test.Comparison with each other shows that the reduced kinetics has the ability to represent efficiently the reaction mechanisms of detailed element reaction model.Some difference between the experimental data and calculated results with detailed kinetics indicates the modifications of the detailed kinetics is needed.
