Definition of green chemistry
“Generation of new products and its process that
reduce or eliminate the use or generation of
Hazardous material”
Chemical
Process
Why do we need
Green Chemistry
• New environmental problems
• Harmful unexpected side effects
• A famous example is the pesticide DDT.
Is there any
advantages…??????
 Eco-friendly
 Energy efficient
 Less wastages
 Fewer accidents
 Safer products
 Easier cleanup
 Healthier work places
 More efficiency
 Lower cost of production and regulation
Principles of Green chemistry
• Waste Prevention
• Improve Atom economy
• Less hazardous chemical synthesis
• Designing safer chemicals
• Use Safer solvent & Auxiliaries
• Design for energy efficiency
• Design for Degradation
• Use of Renewable Feed stocks
• Avoid chemical derivatives
• Use Selective catalysts
• Real time analysis for pollution prevention
• Safer chemistry
Bhopal tragedy-A lesson in inherent
safe design
CH3NH2 + COCl2
CH3NCO
OCONHCH3
OH
ALTERNATIVE WAY
COCl2
OCOCl CH3NH2
MIC
targent
molecule
general synthesis
very dangerous
Hazardous solvent replace by eco-
friendly solvent
Organic solvents
• Highly toxic
• Volatile
• Flammable
• Not naturally occurring
• Expensive
• Harm
Water
• Non toxic
• Non volatile
• Non flammable
• Naturally occurring
• In expensive
• Safe
Green process
• Solvent free reactions
• Use Phase Transfer Catalysts
• Micro wave & Ultra Sound
assisted Green synthesis
