Paulanastas is one of the first person involved in green chemistry

Green chemistry prevent pollution at the source

Green chemistry eleminate the hazardous substances

2.History

* Safer,more Responsible To Use

* Prevention of pollution,elimination of toxins no harmful** VOLATILE ORGANIC COMPOUND

3.Advantages:-

> PAULANASTAS & JOHNWARNER PROPOSED 12 PRINCIPLES:-1. PREVENT WASTE:-

4.PRINCIPLES:-

CHEMICALS

& PRODUCTS

2.DESIGN SAFER CHEMICALS & PRODUCTS

3.DESIGN LESS HAZARDOUS CHEMICALSYNTYHESIS

4. USE RENEWABLE FEEDSTOCKS

5.USE CATALYSIS, NOT STOICHIOMETRIC REAGENTS

6. AVOID CHEMICAL DERIVATIVEES

7.MAXIMISE ATOM ECONOMY

8. USE SAFER SOLVENTS & REACTION CONDITIONS

9.INCREASE ENERGY EFFICIENCY

10.DESIGN CHEMICALS & PRODUCTS TO DEGRADE AFTER USE

11. ANALYSE IN REALTIME TO PREVENT POLLUTION

12.MINIMIZE THE POTENTIAL FOR ACCIDENTS

-> 100% carbondioxide blowing agent for polystyrenefoam production

-> Polylacticacid polymerisation products -> Carpet tile manufacture

-> Inter esterfication of Oils & Fats

5.INNOVATION IN GREEN CHEMISTRY

6.WHAT CAN GREEN CHEMISTRY DO..????

AQUEOUS PHASE REACTION:-

EX:- NAILPOLISH, COSMETICS1. 2.

7.SELECTION OF SOLVENT PHASE REACTION S IN GREEN CHEMISTRY

Reations in ionic liquids

EX:- 1-BUTYL-3 METHYLIMIDAZOLIUM CHLOROALUMINATE
