Spinning discs Reactor

In particular, two main streams of PI applications have been identified (i) PI innovations for reactors (e.g., microreactors, monolith reactors, spinning disc reactors, reactive separations) and (ii) PI technologies for more efficient energy transfer (e.g., ultrasound, pulse, plasma, microwave). Several PI technologies offer important potential, but require important fundamental/strategic research to reach proof-ofconcept on the laboratory scale. These PI technologies are ...

More recently spinning disc reactors have been used by Wilson et alP0) to carry out catalytic reactions using supported zinc triflate catalyst for the rearrangement of a-pinene oxide to yield campholenic aldehyde. The results of this study, presented in Table 20.1, suggest that by using a supported catalyst on a spinning disc reactor it is possible to...

Polycondensation reactions that are equilibrium controlled, such as polyesters, could benefit from the thin films generated in the RPB or spinning disc. In these reactions, removal of the coproduct of polymerization, e.g., ethylene glycol, is necessary in order to advance the polymerization, a task that becomes increasingly difficult as the reaction proceeds. The thin films and short residence time of high-gravity devices aid the evaporation and may permit operation at higher temperatures than conventional reactors (50).

These prices are for the spinning disc reactor as just defined in points a to c, including advanced control and data-logging software with computer and flat screen. The following ancillaries are usually necessary for the system, and these may exist, or Triton can recommend units or can supply them integrated into the system.
