Baffled Reactor System Enhances Exothermic & Large Scale Reactions
Product News May 07, 2015
Asynt Ltd., in conjunction with Innovative Physical Organic Solutions (IPOS), has created a Baffled Controlled Lab Reactor system that offers the ultimate in fast mixing / dispersion.
By using specially designed PTFE baffle blades together with a PTFE turbine stirrer, Asynt is now able to offer scientists a new version of their 5000ml ReactoMate Controlled Lab Reactor system which is built to mix reactions more quickly and effectively.
Most reaction vessels used by research chemists employ simple anchor or turbine stirring devices, both of which move liquid very well but usually this is in a circular direction with a vortex created in the centre. Despite this mixing looking dramatic the time for reactants to mix / disperse homogeneously with anchor or turbine stirrers is relatively slow.
This may not be an issue when the reaction under study is slow and non-exothermic however exothermic reactions such as hydrogenation, nitration, polymerization, acid / base neutralization and catalysis, especially those that require efficient cooling, can be seriously affected by slow dispersion during reagent addition. Similarly many reactions that work well in a lab flask often, when scaled up above 1000ml, can also suffer seriously from this dispersion issue.
For a wide range of exothermic and large scale reactions - Asynt’s ReactoMate Baffled Controlled Lab Reactor system has been shown to improve reproducibility of results, increase selectivity and reduce potentially unwanted side reactions as a result of its ability to provide fast mixing and dispersion. The effectiveness of baffled reactors can be seen on a selection of videos at www.asynt.com/product/reactomatereactionsystems/.
In addition to the new 5000ml system, Asynt offers a special reactor lid, baffles and stirrer for customers to use on existing suitable reaction vessels. Other size ReactoMate Baffled Controlled Lab Reactor systems are available as custom orders.
