Principles of green chemistry Flashcards
better atom economy
more of the feedstock is incorporated into the product and less waste products are produced
prevention of waste products
this is better than having to treat and dispose of waste
less hazardous chemical synthesis
using less hazardous chemicals in the reaction
design safer chemical products
chemical products used will be less toxic/hazardous
use safer solvents
minimise the use of organic liquids as solvents
reduce energy usage
develop processes which work at lower T and P
use renewable feedstocks
instead of depleting natural resources
reduce reagents used and the number of steps
this should reduce wastage
use catalysts and more selective catalysts
this should reduce energy usage and often reduces waster products
design chemical products for degradation
when released into the environment they should break down into relatively harmless products
employ real time process monitoring
better monitoring of chemical processes reduces waste products
use safer chemical processes
choose processes that minimise the potential for releasing gases, fire or explosions
