Continuous Flow Synthesis: Laboratory Approach & Protocol for Scale-up

Video   Apr 24, 2015


About the SpeakerDr. Amol A. Kulkarni is currently a Scientist in the Chemical Engineering & Process Development Division at the National Chemical Laboratory (NCL), Pune (India) He obtained his B. Chem. Eng. (1998) and Ph.D. in chemical engineering (2003) from the Institute of Chemical Technology (ICT), Mumbai, Post Doctorate at the Max Planck Inst. Magdeburg (Germany) and IUSSTF Research Fellow at Massachusetts Institute of Technology (MIT), USA .His research works is in the area of design and development of microreactors and exploring their applications for continuous syntheses of pharmaceutical intermediates, dyes, perfumery chemicals and nanoparticles. He has established the first of its kind microreactor laboratory in India. He also works on multiphase boiling reactors, design of fluid devices, new impeller concepts and experimental fluid dynamics.He is the recipient of Young Associate of Indian Academy of Sciences (2011), CSIR Young Scientist Award (2011), Indian National Science Academy's (INSA) Medal for Young Scientists (2009), Young Engineer Award by the Indian National Academy of Engineering (2009), Max Planck India Visiting Fellowship (2008-2012)He has 49 papers in international peer reviewed journals, filed many Indian, US and PCT patents. Actively involved in the industry sponsored design and feasibility projects and also acts as a consultant to a few industries. AbstractProcess intensification is a design philosophy that can lead to substantial benefits in the areas of energy, capital investment, reduced process wastes and safety through radical changes in the processes. Though there are several ways of achieving it, advent of microreactor technology has revolutionized the concept of process intensification. Over last two decades, radical reduction in characteristic flow dimension of the device and hence of the process equipment and subsequently of the process plant has been under exploration and exploitation by developing new, compact multifunctional devices and contacting techniques, which provide very high heat and mass transfer rates and rapid mixing. Typically, microreactors mean the miniaturized and compact process equipment (which include reactors, mixers, heat exchangers, distillation devices, extractors, etc.) which operate in continuous mode. They are used for the reactions and processes where heat transfer, interfacial mass transfer and mixing can help enhance the overall yield in a safer manner. Typically, these are fast and exothermic reactions or the reactions where selectivity is an issue. Representative examples include aromatic nitrations, exothermic oxidations, sulfoxidation, Grignard reactions, Bu-Li chemistry, etc. While the technology is matured in certain application domains, it is still at its infancy in many, including the design and scale-up guidelines. In this talk I will bring out the fundamental of flow synthesis, typical laboratory approach and scale-up guidelines.
