The boiling point of methanol is 64.6 °C, so point the mouth of the tube away from others and avoid overheating, We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads.
This was due majorly for the fact that the filteration system on many of the suction faucets did not work, making for repeated trials while losing parts of product in the process. Heated reaction for 30 minutes after boiling started. Measured 2 mmol of methyl salicylate into conical vial.
Principle: Methyl salicylate (oil of wintergreen) is an organic ester. As of this date, Scribd will manage your SlideShare account and any content you may have on SlideShare, and Scribd's General Terms of Use and Privacy Policy will apply.
Theoretical Yield of Salicylic Acid (SA) (g): (.002038 mol Methyl Salicylate)*(1 mol SA/1 mol Methyl Salicylate)*(138.1 g SA/1 mol SA)= .281 g Salicylic Acid, (.002038 mol Methyl Salicylate)*(1 mol SA/1 mol Methyl Salicylate)*(138.1 g SA/1 mol SA)= .281 g Salicylic Scribd will begin operating the SlideShare business on December 1, 2020 Oil of Wintergreen: Synthesis and NMR Analysis O Introduction: When salicylic acid reacts with methanol in the presence of an acid catalyst, methyl salicylate, or oil of wintergreen, is produced according to the following equation: C OH OH + CH 3 OH H+ C OCH 3 O OH + H 2 O salicylic acid methanol methyl salicylate (oil of wintergreen) Measured 2 mmol of methyl salicylate into conical vial.

Turned off burner when mixture was clear. The type of reaction may be known as condensation reaction because the small molecule of H2O is eliminated from the reactants while the remaining bits of the reactants condense together to give the main product. Michael Banales Melting Point of the recrystallized salicylic acid: 125-130ᵒC. I have been using it since last year. Kaitlin Saloky Purpose The purpose of this lab was to convert acetylsalicylic acid to methyl salicylate while monitoring the reaction progress using TLC. Rashid Alsuwaidi In a previous experiment, we have used the Fischer esterification reaction to produce isopentyl acetate from an acid (acetic acid) and an alcohol (isopentyl alcohol).
