Green chemistry Flashcards
Define green chemistry
The design of chemical products and processes that reduce or eliminate the use and generation of hazardous compounds
list the Three great challenges
sustainable energy, renewable stocks, hazardous substances
Risk is a function of…
hazard and exposure
Define Auxiliary substances
things used in reactions solvents, dispersing agents, separation agents that are not in the final product.
why are Catalytic reagents are better than stoichiometric reagents?
they lower reaction barrier, less energy required.
3 components of Hazard assessment
Potency, severity, reversibility
Effects on local environment
- Acid rain
- Smog from automobiles and burning fossil fuels
difference between recycling and green chemistry
green chemistry more focused on preventing hazardous compounds from being put in the environment.
Effects on global environment
climate change
List the Life cycle impact categories
- Natural resources
- Ecosystem-water
- Ecosystem-atmpsphere
- toxicity
