Title : HPA modified clays A remarkable green catalysts in organic synthesis


Clays modified with Heteropoly acids (HPAs) have attracted much interest as green catalysts for organic synthesis. Heteropoly acids (HPAs) have several advantages over liquid acid catalysts such as noncorrosive, environmentally benign and due to their strong acidity HPAs have attracted much interest as the catalyst when used with montmorillonite and bentonite clays. Green chemistry focuses on advencement in techniques to prevent pollution and reduce consumption of hazardous chemicals. The development in this area may involve clean synthesis, ecofriendly methods, solvent free synthesis, green catalysts and avoiding the use of hazardous reagents in chemical methods. For the the present study, heteropoly acid (HPA) modified montmorillonite & bentonite clays have been synthesized by swelling and pillaring of clays. Modified clays possess qualities such as good thermal stability, high acidity and high oxidising ability. These modified clays can be used as solid acid catalysts in reactions such as Deoximation of oximes of aldehydes and ketones, synthesis of acetal derivatives of aldehydes and ketones, synthesis of coumarin derivatives etc. For coumarin synthesis, these clays have been found to be efficient and reusable catalysts.


Dr. Chandra Mohan obtained his Ph.D degree in the field of “Schiff based metal complexes and their applications as Chemical Sensors” from Guru Gobind Singh Indraprastha University, Delhi, India in 2017. He has done M.Phil in Inorganic Chemistry from Delhi University and performed his research work on “Heteropoly acid intercalated clays as catalysts” in 2009. He has keen interest in research and development activities. He has 6+ years of teaching experience and about 8 years of research experience. He has published 10 research papers in reputed journals and has presented 10 research papers in various conferences and workshops held in India. He is an awardee of a national fellowship from University Grant Commisiion Delhi for his Ph.D. degree. He was also invited for a lecture from Sensor Lab, University of the Western Cape, Bellville, South Africa in May 2015 and as keynote speaker in the International conference at Imperial College London, UK in September 2018. Presently he is a reviewer & editorial member of 7 International Journals and 8 scientific bodies in India and abroad.
