摘要：采用动态热重法对ＰＶＣ热解脱氯反应动力学进行了研究,对不同升温速率下ＴＧ曲线采用不同方法分析,计算出反应速率常数、反应级数、活化能等脱氯反应动力学参数,并推断出反应机制．分析结果表明,ＰＶＣ热解存在两个阶段,氯原子主要在２５０℃－３００℃之间以ＨＣｌ的形式释放,且反应为一级反应．
The pyrolysis dechlorination of PVC (polyvinyl chloride) was studied by using thermo-gravimetric technique. The kinetic parameters such as activation energies, reaction orders and pre-exponential factors under nitrogen atmosphere were calculated by applying various integral and diffe-rential methods. The results showed that the PVC thermal degradation is a two-step process. The first step mainly involves dechlorination of the polymers. HCl is the main volatile product and this reaction can be seen as a first-order reaction.
