Unformatted text preview: value of 135. We suspect that any impurities in the sample are reminiscent reactants. The Rf value we got for our product showed two spots one at .8 and one at .5. We believe that the one at .8 contains some of the reactant as it has the same Rf value as that of Acetic Anhydride. We think that the Rf at .5 is representative of either un reactive Salicylic acid. The IR spectrum for the reactant salicylic acid and our product had some significant differences. There are a couple of peaks from the 3000to 3200cm-1 range for the salicylic acid, which is not present in the product, indicating that the hydroxyl group from salicylic acid is no longer present in the product. The peak at 1749cm -1 indicates the presence of an ester group, which is also not visible in the reactant. Therefore, I conclude that we successfully created Aspirin...
