Defination of Green Chemistry :. It focus on designing chemical products and process that are eco-friendly. It aims to reduce production of hazardous substances. It has 12 principles. One of its important principle is designing safer chemical solvents.

Principle : Designing Safer Chemical Solvents. New chemicals should be designed with great effectiveness and new approaches to minimize the toxicity and harm to the environment. Chemical products should be designed to effect their desired function while minimizing the their toxicity..

EXAMPLES. DDT is replaced by organic pesticides. By facilitating detoxification:benzene By Isosteric Substitution:Carbon with Silicon.

APPLICATIONS. Cleaner air: Less release of hazardous chemicals to air leading to less damage to lungs Cleaner water: less release of hazardous chemical wastes to water leading to cleaner drinking and recreational water Plants and animals suffer less harm from toxic chemicals in the environment Lower potential for global warming, ozone depletion, and smog formation.

Conclusion :. The ultimate aim of green chemistry is to entirely cut down the stream of chemicals pouring into the environment. This aim seems unattainable at present, but progress in the green chemical research areas and their application through successive approaches will certainly provide safer specialty chemicals and much more satisfactory processes for the chemical industry..
