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 organic layer, pour out the aqueous washing (through the top), then refill the funnel with the organic layer. Repeat the washing process twice more, but using 5% sodium bicarbonate instead of water. Finally, collect the washed organic layer in a dry Erlenmeyer flask. Dry the organic layer with Na2SO4. Decant the clear liquid from the drying agent into a round bottom flask and connect to rotary evaporator to remove organic solvent.

Procedure Your mission is to separate a mixture of trans-cinnamic acid, 4-phenylphenol, and nicotinamide by extraction. Start by dissolving/suspending two grams of the mixture in approximately 50 mL of diethyl ether. (Caution: Diethyl ether is extremely flammable! Extract the ether twice with -25 mL of 5% HCl and then twice with -25 mL 5% sodium bicarbonate. It...
