PRACTICAL APPROACH TO GREEN CHEMISTRY

Objective: The basic principles of green chemistry addresses various issues related to synthesis of chemical compounds: planning organic synthesis to maximise yield, prevention/minimization of waste, atom economy, the use of less lethal chemicals, use of safer solvents, renewable starting materials, energy efficiency and use of green catalysts. The objective of this study is to elaborate the practical approach of green methods.Methods: In this paper, we elucidate some important common syntheses having green procedures which can be used in the fields of pharmaceutical chemistry and other fields as well.Results: Green chemistry principles follow up to reduce pollution and environmental degradation by utilizing eco-friendly, non-hazardous, reproducible and efficient solvents and catalysts in the synthesis of drug molecules, drug intermediates and in researches involving synthetic chemistry. The paper also approaches green methods in which microwave radiation can be used as an energy efficient tool.Conclusion: Experimental procedures are gathered from educational journals and laboratory manuals and are viewed in the light of efficacy of green chemistry principles.
