摘　　要：化学反应工程研究化学反应机理和反应器设计。在反应器设计过程中,反应动力学极为重要。常规的教学内容一般重点讲授在理想化的间歇釜反应器中测量液相(均相)反应动力学的方法和步骤。但是,实际的液相反应过程往往很难实现实时的原位测量,整个过程也常会带有气液传递影响。本文以乙炔法合成N-乙烯基吡咯烷酮的动力学研究为例,解读如何将反应工程基础知识的理想化处理与实际体系相结合来综合解决工程问题。Chemical Reaction Engineering(CRE)mainly studies the chemical reaction mechanism and reactor design.The reaction kinetics plays an important role in the reactor design.Conventional teaching generally focuses on the methods and procedures for measuring liquid-phase homogeneous reaction kinetics in an ideal batch reactor.However,in the actual product production process with gas-liquid transfer effects,it’s often difficult to achieve in-situ measurement.In this paper,the study on the kinetics of the synthesis of N-vinylpyrrolidone by acetylene method is used as an example to describe how to combine the idealized treatment of the basic knowledge of reaction engineering with the actual system to solve engineering problems.
