  1. ATOM ECONOMY • Chemical companies must produce as much product as possible

  2. ATOM ECONOMY • Chemical companies must produce as much product as possible • use reactions with a high yield • - make as least waste as possible

  3. 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:

  4. 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

  5. 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 Need to maximise atom economy: RAM of useful products x 100% RAM of start reactants

  16. % Atom economy = RAM of useful products x 100% RAM of all products

  17. % Atom economy = RAM of useful products x 100% RAM of all products % Atom economy = 80 x 100% = 120

  18. % Atom economy = RAM of useful products x 100% RAM of all products % Atom economy = 80 x 100% = 67% 120

  19. % Yield = mass of useful products x 100% mass of all products

  20. % Yield = mass of useful products x 100% mass of all products % Yield = 140 x 100% = 200

  21. % Yield = mass of useful products x 100% mass of all products % Yield = 140 x 100% = 70% 200

  22. 60 g (A) …………………80 g (C) at 100% Yield

  23. 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.

  24. 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.

  25. 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
