When salicylic acid combines with methanol it becomes the ester known as methyl salicylate or oil of wintergreen. This esterification is generally catalyzed by sulfuric acid in the presence of heat. 1.) If you couldn’t use sulfuric acid, would there be any other ways to speed up the reaction (heat, pressure, radiation, ultrasound, etc)? 2.) What other acids might work as a catalyst? 3.) Would carbonic acid catalyze the esterification? Why or why not?

Create a separation scheme flow chart/diagram to isolate methyl salicylate from a product mixture containing the following: Methyl salicylate, methanol, concentrated sulfuric acid. Lab procedure for separation: Extract with 25mL dichloromethane. Drain the bottom organic layer into a beaker. Repeat the extraction with another 25mL portion of dichloromethane, isolate the bottom layer, and then combine it with the first dichloromethane extract. Pour the combined extracts back into the funnel and wash the solution with 25mL of water. Drain the lower...

An experiment performed using solid to liquid extraction, liquid-liquid extraction, heating, and recrystallization to isolate caffeine, was not totally successful due to their being very little to no product of caffeine left when the time came to recrystallize the pure caffeine. During the experiment what could of caused there to be not enough caffeine to recrystallize it? ethyl acetate was used as the organic solvent hexane and acetone was used to recrystallize the crude caffeine, through mixture and boiling. Could...
