Understanding Flow Chemistry
Flow chemistry can also be referred to as plug flows or microchemistry. A pipe or a tube is the devices that are used to run a chemical reaction which is thus known as flow chemistry. Reactive components are pumped together at a mixing junction and flowed down a temperature controlled pipe or tube. 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.
Faster reactions offered by flow chemistry are some of its major advantages. Since flow reactors can be easily pressurized then this will allow the reactions to heated 100 to 150 degrees above normal boiling points thus creating reaction rates that are 1000 times faster, this whole process is known as super-heating. Secondly cleaner products are achieved by when flow reactors enable excellent reaction selectivity. 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. flow will focus on concentration of flow reagents and their ratio of their flow rate, unlike batch which focuses on the concentration of chemical reagents and their volumetric ratio.
Reaction products existing in a flow reactor can flow into aqueous work up a system and this important since it allows it to be analyzed in line or by sampler or diluter. Automation will allow plug flows to offer Rapid reaction optimization by enabling quick variations of reactions conditions on a microscopic scale. By maintaining excellent mixing and heat transfer scale-up issues are also minimized. Flow chemistry will also enable reaction conditions not possible in the batch such as a five-second reaction at 250 degrees. Electrophile high temperature is made possible by instantly addition multistep procedure such as rapid temperature deprotonation.
Syrris is one of the largest examples of flow chemistry.Flow chemistry reactors also exist as spinning disk reactors, spinning tube reactors, multicell flow reactors and oscillator reactors. 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. the establishment of a start-up and shut up times is essential in the chemistry flow process.
