2Continuous flow systemABSTRACT In the modern time now, the flow chemistry has been introduced to effectively help in modern organic chemistry to strengthen, improve the monitoring of the chemical reactions progress and to highly enhance on the quality of yields or end products. Nevertheless, based on this introduction slight challenges are being experienced on the likelihood of correct determination ofthe scale up, and partial information in regard to the design of this process and efficiency of the evaluation. These reports enlighten some approaches of the flow synthesis based on certain form of scale up and manufacturing issues. The essential practical data and its application in form of the results are demonstrated.

4Continuous flow systemIntroduction The developing and interesting topics that are based on micro reactors and continuous flow chemistry technology are observed to merge together, chemical engineering, green chemistry andorganic synthesis. The context on continuous flow chemistry is a constantly interdisciplinary topic, that will be reflected on chemical reactivity, fluid dynamic, reactor design and mass and heat transfer(Kockmann, Gottsponer &Roberge, 2011, p.718-726).The tradition methods of batch process were majorly used by specialist and pharmaceutical chemistry because of the following advantages;1.They were versatile.2.They were flexible in terms of scheduling and planning. 3.They were easily traceable in regard to specific batches, hence regulation problem were easily determined. Similarly the batch process had certain disadvantage as follows; 1.The problem encountered through heat and mass transfer made the process of scaling up to be difficult. 2.The method required substantial intermediate storage capacity throughout the progressiveprocesses stages; hence they required enormous records on the feedstock of the organic chemicals and delicate intermediates. In comparison to batch process, the continuous flow chemistry will classically require (Jolliffe &Gerogiorgis, 2015, p.175-191); 1.Small volume size of equipment.2.Less human interferences. 3.In particular if we refer pharmaceutical industry, the volatility life of its products will require a successful time to for marketing its products4. The pharmaceutical products require enough materials to be used for clinical trials with minimum merits in order to lower the production cost, minimize waste and reduce marketing time of the drugs.5.The continuous flow reactors deliver higher yields, and in the process there is reduction in percentage of energy and solvent waste to about 90%.The safety and sustainable improvement of fine chemical together with the pharmaceutical industry is developed through implementation of typical processes, that are cable to subdue the safeness and regulation that is based on the modern technology. The adoptive methods of safer production process will create synthetic routes that are categorized with lower factor of waste products.
