The atom economy of a chemical reaction is a measure of the amount of starting materials that become useful products. Inefficient, wasteful processes have low atom economies. Efficient processes have high atom economies, and are important for sustainable development, as they use fewer natural resources and create less waste.
Companies want to maximise as much product as possible to allow for maximum profits. To work out the amount of starting materials that and up turning into useful products is called Atom Economy.
% of atom economy = Mr of useful products x100
In green chemistry: Atom economy Of these principles, “atom economy,” originally suggested by American chemist Barry Trost in 1973, became a central concept among green chemistry researchers. Atom economy was designed to overcome the limitations of the traditional concept of “yield,” the amount of final products, which was.
(a) Calculate the atom economy and reaction efficiency of your synthesis. (b) Describe some green features of your synthesis, and any that aren’t so green. Atom economy is a measure of the number of atoms from the starting materials that are present in the useful products at the end of the chemical process. Atom economy is the second principle of green chemistry The ideal atom economy, known as 100% atom economy, for a chemical reaction is taken as the process where all reactant atoms are found in the desired product. Unfortunately, this method is not suitable for multifarious monomers and the polymeric products obtained often show large polydispersity with low atom economy. (20,21) In 2017, Sharpless et al. Reported an efficient sulfur(VI) fluoride exchange (SuFEx) click reaction for the synthesis of polysulfonates, (22−24) which is a big step forward.
Total Mr of all products
e.g. C2H5OH -> C2H4 + H2O
Atom Economy Ppt
Mr: C2H5OH = (12×2) +(1×6) + 16 = 46
C2H4 = (12×2) + (1×4) = 28
H2O = (1×2) + 16 = 18
Atom Economy Is Quizlet
Atom Economy = 28 x100 = 61%
(28+18)
