Glacial acetic acid 150 mL 695092 Sodium bicarbonate (5%) 300 mL S6014 Sulfuric acid, conc 5 mL 258105 Sodium sulfate, anhyd. 25 g 258105 Comparative Analysis of Traditional vs. Suggested Experiments Greener method introduces the concepts of bio-based resources and renewable raw materials Greener method produces the product, which can be used in diesel engines, along with aqueous waste Traditional esterification reaction uses various alcohols all have moderate EH&S profiles The comparative costs for all reagents per 100 students for this experiment is $41 for the Greener method and $21 for the Traditional method. Actual cost will vary. Reduction (per Benefits “Greener” 100 students) 1400 mL biodiesel product Greener method 2.3 mL aq. waste 100 g solid waste 525 mL aq. Traditional method 25 g waste Additional Resources & Further Reading The following are additional greener alternative laboratory experiment options:
