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.

Ind. Eng. Chem. Res. 1999, 38, 1075-1082 The mixing quality of a single mixing unit and mixer arrays having various designs was characterized. A known test reaction for mixing quality had to be optimized, since a much higher sensitivity as for the characterization of macroscopic mixers was needed. This adapted test reaction allowed not only the characterization of the mixing quality but also analysis of the homogeneity of the flow distribution b...

Chemical Engineering Communications, (2001) The DISMT (Dual Indicator System for Mixing Time) mixing time/distance diagnostic encodes semi-quantitative visualization of liquid/liquid mixing processes in color changes. In DISMT, two liquids, one red and one blue, are mixed to produce a yellow liquid. Through appropriate choice of the acid-base indicators used, and the initial pH’s of the two solutions, the yellow liquid appears only in those regi...
