ABSTRACT

The present review work focuses on the importance and economic development of green chemistry. It is new branch in chemistry dealing with reduction of harmful and toxic chemicals in the synthesis and replacing it with eco friendly methods. The principle of green chemistry with various benefits have been discussed to understand the basic requirement for replacement of conventional synthetic method with green chemistry synthesis. To describe it the synthetic approach for the synthesis of acetanilide has been discussed and compared.[1] Chemistry brought about medical revolution till about the middle of twentieth century in which drugs and antibiotics were discovered. The world’s food supply also increased enormously due to the discovery of hybrid varieties, improved methods of farming, better seeds, and use of insecticides, herbicides and fertilizers. The quality of life on earth
became much better due to the discovery of dyes, plastics, cosmetics and other materials. Soon, the ileffects of chemistry also became pronounced, main among them being the pollution of land, water and atmosphere. This is caused mainly due to the effects of by-products of chemical industries, which are being discharged into the air, rivers/ oceans and the land. The use of toxic reactants and reagents also make the situation worse. The pollution reached such levels that different governments made laws to minimize it. This marked the beginning of Green Chemistry by the middle of 29th century. Green Chemistry is defined as environmentally benign chemistry.[1]
