 Salcyclic Acid Synthesis Dialogue Essay

IX. Discussion:

In this test we carried out an organic synthesis with the intent to prepare salicylic acid coming from methyl salicylate. Our research compared the synthesized compound, salicylic chemical p, from two different chemicals, wintergreen oil and benzene. We began the test by first synthesizing disodium salicylate from the wintergreen oil simply by heating through reflux applying 1 . 53 grams of methyl salicylate and 12-15 milliliters of 6M sodium hydroxide. In this process the sodium ions replaced the hydrogen ion and the methyl ion on each of your on the o2 as illustrated in number 1 . 1238250191135DepronationAcid/Base Rxn00DepronationAcid/Base RxnFigure 1: 5067300110490Elimination

With this process the hydrogen ions from the sulfuric acid substituted the sodium ions on the disodium salicylate as known in physique 1 . According to Denton (2013) " the relationship between an OH ion and carbonyl carbon atom is accompanied by the breaking of a π bond in the carbonyl group. That π bond is reformed when a relationship to the –OCH3 is busted. ” This is observed even as were able to develop salicylic acidity as known in figure 1 . Following this further, the obtained salicylic acid was then filtrated and underwent recrystallization for purification for additional analysis. Subsequent we compared the burning points of the synthesized salicylic acid by wintergreen petrol and benzene. We were in a position to determine the average melting point for the wintergreen oil to be 161. 2 °C and 161. 1 °C for benzene. Literature shows that if he melting level of a compound melts more than a narrow selection (1-2°C or perhaps less) for a heat close to the books value (159. 0 °C), it is likely pure (Lehman, p. 306). From this guide we were...
