TN269 – Mixing with mechanical stirring Private content

In most organic reactions, the stirring of the mixture has to be maintained during the reaction for a good homogeneity of the mixture and for improving the efficiency of the reaction. In industrial reactors, large amounts of chemical products are continuously mixed by means of mechanical stirrers. It can be the reaction of two liquids giving a crystallized solid, or the mixing of a liquid and a solid giving another solid, or also reactions between solids. In all cases, stirring and sometimes strong stirring, is needed.
SETARAM has designed a mixing vessel linked with a mechanical stirrer in order to simulate types of reactions and to evaluate what is the heat evolved during mixing and reaction. These data are helpful to design the reactor and its cooling system.
