A REVIEW ON GREEN APPROACH IN CHEMISTRY

Jyoti Mathela* and B.K Singh

Abstract

Green chemistry advocates the set of principles and methodologies that can reduce the generation of hazardious substances in the manufacture and application of chemical products. 1. By modification of the traditional synthesis reactions we can arrive at the same final product, yet reduce or eliminate toxic starting materials, by-products, and wastes. 2. Green chemistry tools include choosing alternate starting materials, reagents, solvents, process alternative process analytical chemistry and catalysts. Green chemistry focuses on the minimizing the environmental impacts of hazardous chemicals substances. It is based on the effective ways to reduce, remove or rectify the existing toxic effects of hazardous substances generated as a result of manufacture and the use of chemical substances. By using sustainable means of waste management and by limiting the existing use of hazardous substances, the devastating impacts of chemical substances can be prevented. This review covers subjects relating to reducing the environmental impacts of chemical substances and fuels by developing alternative and sustainable technologies that are non-toxic to living things and the environment .It shall also focus on Alternate Energy Technologies, Biofuels, Green engineering and Green solvents.The application of innovative technology to establish industrial procedure, designating greener, safer chemical synthesis, designing greener and safer chemical manufacturing processes, Microwave assisted and Ultrasound assisted synthesis,Green synthesis. This review focuses on the modification in some traditional reactions by changing the solvents b green solvents like water or by alterations in temperature which leads to better environment friendly products. This review is an attempt to compile all major work towards role of green chemistry to maintain the sustainability and environmental protection.

Keywords: Microwave assisted reactions, Ultrasound assisted reactions, Biofuels.
