Chem 104A Abstract: In order to determine the best conditions from the reaction of ferrocene and acetic anhydride, the four environmental conditions were varied to find the maximum product yield. Thin layer chromatography was the method used to find the results to determine which conditions produce the ideal amount of monoacetyl ferrocene. The best conditions determined are 5mL acetic anhydride, 7 drops of catalyst, for 20 minutes at 70°C. Introduction: While performing this experiment two major objectives will be met. These objectives are to perform controlled synthesis reactions and evaluate the effect of four different variables on the yield of acetyl ferrocene. The problem for this experiment is to determine the best set of conditions for the production of monoacetyl ferrocene from ferrocene and acetic anhydrate. There are four conditions that will be investigated. Among these conditions are temperature, reaction time, amount of reactant, and amount of catalyst. Theses conditions are known as the control set of conditions. Since there are four members needed for this lab one member will be required to vary one of the four conditions. Each student should obtain the same results for the controlled reactions. Another reaction needed to be performed is called the blank reaction. This means the condition needs to be set to zero. Finally every student will perform two more reactions where the variable is set at a different value, rather than the controlled and blank reactions. After performing the experiment we were able to retrieve the masses of the products to use in the next part of the lab. The second part of this experiment was chromatography separation. We used a technique called
