1. Green Chemistry Making the connection between green chemistry and safety at the undergraduate level Robert M. Hanson St. Olaf College Northfield, MN 55057 hansonr@stolaf.edu 244 th ACS National Meeting, Philadelphia, Pennsylvania August 21, 2012

2. Green Chemistry My Goals Today Emphasize the connection between green chemistry and safety. Make that case that GC and safety nicely complement each other. Show you what we are doing at St. Olaf College in both these areas.

3. Green Chemistry Good reasons to teach about green chemistry

4. Green Chemistry Good reasons to teach about green chemistry

5. Green Chemistry Good reasons to teach about green chemistry

6. Green Chemistry Good reasons to teach about green chemistry

7. Green Chemistry Good reasons to teach about green chemistry

8. Green Chemistry Good reasons to teach about green chemistry Green chemistry is all about purposeful design. Green chemistry demands accountability. Green chemistry resonates with student creativity and interest in caring for the environment and for the future.

9. Green Chemistry Purposeful Design Green chemistry requires a consideration of intent. –Which of the products is the desired product? –Is there a better way accomplish the same result? Involving fewer hazards Involving less waste

10. Green Chemistry Question: What is the balanced chemical equation for this reaction? Accountability

11. Green Chemistry Question: What other products are formed? Accountability

12. Green Chemistry Accountability Green chemistry requires consideration of all of the inputs and outputs. Atom Economy = 40% before… …after

13. Green Chemistry Accountability Green chemistry requires consideration of all of the inputs and outputs. Experimental Atom Economy = 26% before… …after

14. Green Chemistry Creativity Green chemistry considerations suggest valuable alternatives. Atom Economy 84% Exp. Atom Economy 80%

31. Green Chemistry Green Chemistry At St. Olaf Lessons learned: Students need help learning how to be accountable for the chemistry they do.

32. Green Chemistry Green Chemistry At St. Olaf Lessons learned: Introducing green chemistry provides a context for discussing safety, including MSDS sheets, health, and environmental hazards.

33. Green Chemistry Green Chemistry At St. Olaf Lessons learned: Students start asking important questions.

34. Green Chemistry Green Chemistry At St. Olaf Lessons learned: Faculty start asking important questions.

35. Green Chemistry Green Chemistry At St. Olaf Lessons learned: Faculty and students start talking. Just talk about the different approaches you might take … I think that's kind of how I got it or at least that's how it was when I took it with [organic chemistry lecture professor] where we were just talking, you know, about things and we would just talk about it a little bit and the advantages and disadvantages of it with regards to safety…

36. Green Chemistry Green Chemistry At St. Olaf Lessons learned: Risk = f (hazard, exposure)

37. Green Chemistry Green Chemistry At St. Olaf Lessons learned: Risk = f (hazard, exposure) Awareness = f (interest, exposure)
