We present a flow concept to measure fast gas–liquid reaction kinetics. A tube-in-tube reactor design with semipermeable Teflon AF-2400 tubes is adopted to achieve fast gas–liquid mass transfer without direct contact of gas and liquid. By performing a steady-state flux balance of both gas and liquid flowing into the reactor and developing a mathematical model based on the film theory, the reaction kinetic parameters can be determined with excellent precision with the use of only a single gas flow meter. Reactions of CO₂ with alkanolamines and ozonolysis of organics serve as case studies to assess the ability of the technique to resolve reaction kinetics in situ. The proposed strategy presents a new opportunity for the study of fundamental aspects of gas–liquid reactions in a simple, safe, automated and high-throughput manner.

流动中快速气液反应动力学的测定

我们提出了一种流动概念来测量快速的气液反应动力学。采用具有半渗透性的Teflon AF-2400管的管中管反应器设计，可实现快速的气液传质，而无需气液直接接触。通过对流入反应器的气体和液体进行稳态通量平衡并建立基于薄膜理论的数学模型，仅使用一个气体流量计即可以极高的精度确定反应动力学参数。CO ₂与链烷醇胺的反应和有机物的臭氧分解用作案例研究，以评估该技术解决原位反应动力学的能力。提出的策略为以简单，安全，自动化和高通量的方式研究气液反应的基本方面提供了新的机会。
