A new reaction pair for micromixing measurements in gas-liquid systems with large vapour generation

This paper presents details of a new test reaction system suitable for sparged aqueous systems at temperatures up to 100oC. This system, which is easy to use, provides the basis for experiments carried out in a standard semi-batch stirred tank reactor agitated with a Chemineer CD-6 hollow-blade impeller. The quantitative characterisation provided by liquid micromixing sheds light on the effect of temperature, and hence vapour pressure, in the operation of gas-liquid reactors.
