Atom Economy Concept
Formula
Atom Economy = (MW of Desired Product / Σ(MW of All Reactants)) × 100%
- • Measures efficiency of atom utilization
- • Higher values = more efficient reactions
- • Maximum = 100% (all atoms in product)
- • Important for green chemistry
Green Chemistry Principles
- • Minimize waste generation
- • Maximize atom efficiency
- • Reduce environmental impact
- • Improve sustainability
- • Lower production costs
Typical Atom Economy Values
Excellent (90-100%)
- • Addition reactions
- • Rearrangements
- • Diels-Alder reactions
- • Cycloadditions
Good (70-89%)
- • Substitution reactions
- • Many organic syntheses
- • Catalytic reactions
- • Some eliminations
Poor (<70%)
- • Elimination reactions
- • Multi-step syntheses
- • Reactions with byproducts
- • Traditional methods
