Matt Grosjean Green Chemistry Exercise 1 Chem 200-1 TW 5.30 April 16, 2008 In order to focus more attention on the waste products that are formed in synthesizing a compound, Barry Trost of Stanford University developed the concept of atom economy. This concept finds the amount of atoms incorporated in the development of the desired compound and how many atoms are wasted. One example of this is in the synthesis of ibuprofen. Ibuprofen is the active ingredient in many analgesic and inflammatory drugs such as Advil, Motrin, and Medipren. Beginning in the 1960s, ibuprofen was produced by a six-step synthesis with an atom economy of only 40 percent. This meant that less than half (40 percent) of the weight of all the atoms of the reactants were incorporated in the ibuprofen, and 60 percent were wasted in the formation of unwanted by-products. The annual production of approximately 30 million pounds of ibuprofen by this method resulted in over 40 million pounds of waste. But during the 1990s, the BHC Company
