Title
Synthesis of dendrimer for catalysis and chromatographic separations
Abstract: The main role of chemist is to design and improve processes for the production of chemicals foods pharmaceuticals and many other products used in everyday life. In this talk a lot of attention has been given to dendrimer synthesis which is insoluble monodisperse macromolecules with globular structures. Modified glycidyl methacrylate resin (dendrimer) were prepared by cross-linking and/or the formation of composites with unique physicochemical properties as potential adsorbents for a wide-ranging applications in green chemistry. This talk will highlight some application of modified resin with diverse structure and physicochemical properties relevant to adsorption-based processes. The relevance to green chemistry relates to the treatment of waste water and separation of sugar molecules due to the tunable properties of modified resin. In this talk Firstly I will discuss the development of highly branched iminodiacetic acid (IDA) dendrimer which was used as a catalyst to afford β-amino alcohols and for the removal of heavy metals from waste water. We have also developed amine dendrimer for selective separation of rebaudioside A on preparative scale. With this process high purity could be achieved which fulfilled the requirements of the food and beverage industry. Secondly I will focus on the use of hydrophobic protein for the synthesis of silver nanoparticle (AgNPs) under incandescent light and its immobilization on methacrylate resin which was found effective for the disinfection of waste water.Bio: Mrs. Richa Tiwari has done her B. Sc Chemistry in 2008 and M. Sc Drug chemistry in 2010 from university of Pune. She started working as a lecturer in Drug Chemistry department Ahmednagar College Ahmednagar from 2010-2011. She has also worked as assistant trainee in Medicinal Chemistry Department Sai Advantium Pharma Ltd. Pune from 2011 to 2012. After that she joined Ph. D under the guidance of Dr. Sandeep Kale in the DBT-CEB institute of Chemical Technology Mumbai. Her thesis work was mainly focused on the synthesis of dendrimer for catalysis and chromatographic separations. Her work on disinfected and heavy metal free water was selected for TOP-20 BEST INDIA 2015. She had been invited by several national and international conferences where she presented her research work.
