Yield is not enough !!!
• Yield = % of maximum possible quantity of
product
• But !!!
• Ignores auxiliaries (reagents, catalysts, solvents,
etc)
• Ignores work-up, purification
• Ignores energy used, hazards involved, toxic
chemicals
19


• For example:
• A typical textbook procedure for oxidation

reaction
• Yield = 55%
• Weight of product = 15g
• But !!!
• Involved 900 g inputs
• Produced 800 g of waste

What is green chemistry?
• The design of chemical products & processes
that reduce or eliminate the use or generation of
hazardous substances

• Discovery & application of new chemistry /

technology leading to prevention / reduction of
environmental, health & safety impacts at source

History
• Pollution Prevention Act 1990
• Green chemistry Began in 1991 at
Environmental Protection Agency, Paul
Anastas
• 1996 Presidential Green Chemistry Challenge
Awards
• 1997 Green Chemistry and Engineering
Conference
• 1999 Journal “Green Chemistry”
• Chemical & Engineering News
• 2001 Journal of Chemical Education

12 Principles of green chemistry
(Paul Anastas & John Warner)

1. Prevent waste: Design
chemical syntheses to
prevent waste, leaving
no waste to treat or
clean up
