Investigation of mixing in a rotor shape modified Taylor-vortex reactor by the means of a chemical test reaction

The macro- and micromixing properties of a continuous flow Taylor-vortex reactor can be optimised by changing the conventional cylindrical rotor geometry into a novel ribbed one. A chemical test reaction, the micromixing-sensitive alkaline saponification of ethylacetate with separately fed reactants, was used to probe the mixing performance down to the molecular level. Experiments were performed in a continuous flow Taylor-vortex reactor equipped either with a conventional cylindrical rotor or with a novel ribbed rotor in a wide hydrodynamic range of 150
