chemical companies must produce as much product as possible atom economy
TRANSCRIPT
Chemical companies must produce as much product as possible - use reactions with a high yield- make as least waste as possible
ATOM ECONOMY
Chemical companies must produce as much product as possible - use reactions with a high yield- make as least waste as possible
Good news for:
ATOM ECONOMY
Chemical companies must produce as much product as possible - use reactions with a high yield- make as least waste as possible
Good news for:* company profits* environment - uses less of world’s resources
ATOM ECONOMY
Chemical companies must produce as much product as possible - use reactions with a high yield- make as least waste as possible
Need to maximise atom economy:
RAM of useful products x 100% RAM of start reactants
Good news for:* company profits* environment - uses less of world’s resources
ATOM ECONOMY
% Atom economy = RAM of useful products x 100% RAM of all products
% Atom economy = 80 x 100% = 67% 120
60 g (A) …………………80 g (C) at 100% Yield
If the yield was only 50% and the same amount of product is required, then ?? x original reactants is needed.
60 g (A) …………………80 g (C) at 100% Yield
If the yield was only 50% and the same amount of product is required, then 2 x original reactants is needed.
60 g (A) …………………80 g (C) at 100% Yield
If the yield was only 50% and the same amount of product is required, then 2 x original reactants is needed.
So if the yield is 75% and the same amount of product is required, then 4/3 x original reactants is needed: = 4/3 x60g = 80g
