摘　　要：化学反应动力学是研究温度、浓度等对反应速率影响的一门学科,对工程指导有着重要意义。然而,目前的动力学研究多是基于恒定温度情况下展开研究的,这对占绝大多数的恒温反应实用,虽也能用于研究变温反应,但与实际反应条件并不相符。本研究方法基于原有方法,做适当调整,简化了实验步骤,且使得分析更切合实际反应情况。全文以DOTP的合成为例,具体说明了研究步骤,且得出了DOTP合成的速率方程,并解得活化能为82.83kJ.mol-1。Chemical reaction kinetics is a subject of studing subject about temperature and concentration on the reaction rate, which has important significance in engineering. However, the current dynamics research is based on the constant temperature, it＇s suit the majority of the thermostatic reaction. Although it also can be used to study the temperature response, but are not consistent with the actual reaction conditions. This research method is based on the original method with some appropriate adjustments, simplified the experimental steps, and makes the analysis more realistic reaction conditions. Take DOTP for example, In the real temperature of reaction, Computing the conversion and concentration at the time when it does not affect the temperature. Determine corresponding rate constants and corresponding series, Get the Kinetics Rate equation. Then Computing the other rate constants at corresponding temperature. Last Computing the activation energy is82.83kJ, mo1-1.
