P141: Comparison of green and standard aldol condensations in an undergraduate organic chemistry laboratory
A solventless aldol condensation demonstrated at the 2011 cCWCS workshop on Green Chemistry is used as a vehicle for introducing green chemistry concepts in an organic chemistry laboratory context. Students experience a combination of pre-laboratory literature work on green chemistry principles and a hands-on comparison of two versions of an aldol condensation. They then compare the relative “green-ness” of the two condensations. It becomes apparent that even a reaction that is relatively green due to high atom economy and the use of a catalyst can be further improved by focusing on the flammability hazards of the solvent and waste reduction.
