Standard Green Chemistry and process engineering tool based on Anastas & Warner's 12 Principles of Green Chemistry.
Calculation Methodology
Atom Economy (% AE) = [ Molar Mass of Desired Product / Sum of Molar Masses of All Reactants ] * 100%. Environmental E-Factor = Waste Mass / Desired Product Mass.
Frequently Asked Questions
Percent Yield reflects experimental operational efficiency, whereas Atom Economy reflects the intrinsic stoichiometric design and how much reactant mass is fundamentally converted into useless waste byproducts.
