It is well known fact that self- sufficiency in food has been achieved in India since late 20th century by using fertilizers and pesticides and exploring improved methods of farming, good quality seeds, irrigation etc.
But over exploitation of soil and excessive use of fertilizers and pest have resulted in the determination of soils, water and air.
The solution of this problem does not lie in stopping the process of development that has been set in; but to discover methods, which would help in the reduction of deterioration of the environment.
Green chemistry is a way of thinking and is about untilising the existing knowledge and principles of chemistry and other sciences to reduce the adverse impact on environment.
Green chemistry is a production process that would bring about minimum pollution or deterioration to the environment.
The byproduct generated during a process, if not used gainfully, and to the environment pollution. Such processes are not only environment u friendly but also cost-ineffective. The waste generation and it's disposal both are enconoically unsound. Utilisation of existing knowledge base for reducing the chemical hazards along with the developmental activities is the foundation of green chemistry.
Have you perceived the idea of green chemistry? It is well known that organic solvents such as benzene, totuene, carbon tetrachloride etc., are highly toxic. Once should be careful while using them.
As you know, a chemical reaction involves reaction, attacking reagents and the medium in which the reaction taken place. Extent of any reaction depends upon physical parameters like temperature, pressure and use of catalyst.
In a chemical reaction, if reactants are fully converted into useful environment friendly medium then there would be no chemical pollutants introduced in the environment.
During a synthetic, care must be taken to choose starting materials that can be converted into end products with yield approximately upto 100 per cent. This can be achieved by arriving at optimum conditions of synthetic.
It may be worthwhile to carry out synthetic reactions in aqueous medium since water has high specific heat and low volatility. Water is cost effective, no inflammable and devoid any carcinogenic effects.
