February 4, 2015 Objective Extract benzophenone from solution Analyze the products of the reaction Set up Alicia's polymerization reaction Description 1. The round bottom was removed from the schlenk line and excess water was not added to the reaction mixture to stop it because the liquid evaporated. Possibly evaporated because the reaction continued past 8 hours. The solid product was dissolved in 1.5 mL ethyl acetate and centrifuged to recover the gold-lysozyme nanoparticles. 2. TLC Analysis A small drop of the sample was analyzed using thin layer chromatography and compared to the mixture before the addition of the catalyst. So far it seems as though benzophenone formed as a product but the yield was not high. In the future, more Au:Lys nanoparticles should be added (possibly 2 mLs) and the reaction mixture should be constantly monitored so that it does not evaporate.
