WM5: Synthesis of Aspirin Flashcards
Why would chemists want to minimise waste products?
Better and cheaper than having to treat and dispose of waste products
Why would we want a reaction to have a high atom economy?
More feedstock is incorporated into the product and less waste products and produced
Why would chemists want to use less hazardous chemical synthesis routes?
Safer for workers, cheaper in terms of safety precautions
Why would chemists design safer chemical products?
Less toxic and hazardous chemicals
Why would chemists want to use safer solvents (e.g. water)?
Easier to dispose of than organic solvents
Why would chemists find synthetic routes which use lower energy routes?
Lower temperature and pressure processes save money
Why would chemists want to use renewable feedstocks for a reaction?
Doesn’t deplete natural resources
Why would chemists use catalysts in reactions?
Generally reduce energy and can be reused in reactions
Why would chemists want to design biodegradable products?
So they can safely break down in the environment
Why would chemists design safer chemical processes?
To ensure we minimise the risk of potential release of gas, fires and explosions
What 3 processes can be used in the process to purify an organic solid?
- Recrystalisation
- Thin Layer Chromatography (TLC)
- Melting point determination
