The Green Oxidation of Borneol to Camphor
The Green Oxidation of Borneol to Camphor Date Conducted: February 8, 2012 April 27, 2012 Abstract: The goal of this experiment was to perform a Green Oxidation of Borneol to Camphor, without the use of Chromium synthesis since it is toxic to the environment. Reagent Table
Just a hot plate and ice bath were used to mix and maintain the temperature of the experiment. Though when drying the product vacuum filtration was used and the set up is as follows: The product obtained from the experiment was g of Camphor. The % yield of the product was as follows. % yield = Mass of obtained X 100 Theoretical value Procedure: The Lab was followed exactly except for using a 25ml Erlenmeyer flask instead of 50ml. Results: |Tarred Vial |Vial and Camphor |Camphor | |11. 943g |11. 79g |0. 036g | Calculations: % yield = 0. 036 g X 100 = 3. 55% 1. 01 g Discussion: The goal of the lab was to produce camphor through the oxidation of borneol. The lab obtained 0. 036g of camphor for a final product with only a 3. 55% yield. During the first part of the lab, creating the oxidant, while maintaining a constant temperature of the mixture, errors could have occurred. For example, little yield could have occurred during this process if the bleach was added to quickly or if very little of the oxidant was created.
During the second part of the lab was successful since a positive test on the K-I starch paper until it was to be neutralized. When adding enough sodium bisulfite a negative test on the K-I starch paper was obtained. Even though there was some product obtained some part of the reaction was now carried all the way through which ended up with very low results.
