Brittney Brown Due: 11-19-2009 Title: Methyl Salicylate Questions Lab Partner: Chelsea Searels 1. 2. 3. Salicylic acid is solid at room temperature has a melting point range between 158 and 161°C. Room temperature ranges between 20 and 25°C. Therefore, melting point of salicylic acid is higher than room temperature resulting in its solid form. On the other hand, methyl salicylate has a melting point between -8 to -7°C. Its melting point is lower than room temperature resulting in its liquid room. 4. Sodium bicarbonate was used in the experiment to wash the product. It neutralizes the acid, sulfuric acid. Mixing the acid and base canceled out their effects on the product. Using sodium carbonate or sodium hydroxide would have resulted in a more basic product, which was not

Unformatted text preview: desired. 5. The reaction of salicylic acid with a catalytic amount of sulfuric acid and excess methanol was heated to distill methyl salicylic. At room temperature, the reaction would have progressed slowly reverting to the desire product, methyl salicylate. A large molar mass excess of methyl alcohol was used because methyl salicylate is derived from a combination of salicylic acid and methanol. It is also soluble in methanol. 6.
