Understanding Flow Chemistry
Flow microchemistry or plugs flows are other names that refer to Flow chemistry. A pipe or a tube is the devices that are used to run a chemical reaction which is thus known as flow chemistry. By pumping a reactive component together at a mixing junction and the flowing down a temperature controlled pipe or tube the microchemistry is achieved. The pumps, therefore, move fluids in a pipe or a tube and where tubes join one other fluid get into contact with each other. Flow chemistry is achieved in a flow reactor which is a device in which chemical reactions take place in micro channels. Large companies in manufacturing can largely and effectively use flow chemistry.
Some of the major advantages of flow chemistry are that it offers faster reactions. Super heating is the process that will allow reactions to be heated 100 to 150 degrees above normal boiling points since flow reactions can be pressurized and thus creating reactions that are 1000 times faster. Secondly flow reactors enable excellent reaction selectivity thus ensuring cleaner products. The surface area to volume ratio is increased by rapid diffusion thus enabling instantaneous heating or cooling, therefore, offering ultimate temperature control. Flow chemistry allows only a small amount of hazardous intermediate to be formed at any instant thus allowing excellent control of exotherms. Batch process focuses on the concentration of chemical reagents and their volumetric ratio while flow focuses on the concentration of flow reagents and the ratio of their flow rate.
Reaction products can be analyzed in line or by sampler or diluter since they exist in a flow reactor and can be flowed into an aqueous flow work up a system. Plug flows through automation will offer rapid reaction optimization by enabling quick variations condition on a very small scale. Scale up issues is also minimized due to maintaining excellent mixing and heat transfer. Flow chemistry will also enable reaction conditions not possible in the batch such as a five-second reaction at 250 degrees. Rapid, low temperature deprotonation followed by instant addition of electrophile high temperatures is made possible in multistep procedure.
One of the biggest examples of flow chemistry is syrris. Spinning disk reactors, spinning tube reactors, multicell flow reactors and oscillator reactors are other types of flow chemistry recators Variety of flow chemistry notes and reactions using flow chemistry systems are demonstrated by range of resources in syrris. The flow chemistry has a few drawbacks among the being it requires dedicated equipment for precious continuous dosing. start up and shut up times must also be established for the chemistry flow process to be effective.
