Quantative Chemistry
Atom economy
-
lot of reactions make many products,
some useful other waste
-
tells us how much mass of reactants is wasted, and how much ends up in desired product
-
100 % means all to desired product,
higher the "greener" the process
Higher
-
only one product - 100%, more product, lower AE
lower
uses up resources quickly, if non-renewable will run out
waste need to be disposed, can be expensive
-
better to use waste products, come up
with reactions with usefel by-products
percentage yield
yield
-
more reactants, more yield by % not affected
-
-
-
High, less waste and less cost, better for industry
never get 100%
-
3 common problems
- not all reactants react ot make product
-
- might be side reaction, eg react with air or impurites
- lose product when seperate from reaction mixture
E.g filter paper, remain in solid or liquid, or when tranferring from one container to another
