Question 29 0.1/1 point You prepare and isolate methyl salicylate (oil of wintergreen). If you began with 1.4262 g of salicylic acid and obtained 1.2210 g of methyl salicylate, what was the percent yield of your reaction?
Questions 1. Draw the structure of methyl salicylate, and say what evidence indicates that methyl salicylate was formed. 2. Draw and compare the structures of acetylsalicylic acid and methyl salicylate. Circle and name the functional groups in both compounds. 3. The fragrance of apricots is due to the ester pentyl butanoate. Write the equation for the synthesis of this ester from the acid and the alcohol. 4. Give examples and names of any other compounds that contain the functional groups...
1. The actual substitution of the methoxy group in methyl salicylate with the hydroxyl group in salicylic acid requires one hydroxide ion, but in all actuality, a minimum of two equivalents of hydroxide ion are required for every one equivalent of the ester in order to achieve the theoretical yield. Explain why. 2.Why does the addition of sulfuric acid to the crude reaction mixture result in the precipitation of the product? Write a balanced reaction equation showing the chemistry that...
what is the purpose of the following in the experiment of Synthesis of Methyl Salicylate 1. Phosphoric Acid 2.Methyl Anthranilate 3. Sodium Nitrite 4.Diethyl Ether 5.Nitrogen what is the reaction scheme
Methyl salicylate could be deacylated using sulfuric acid. What is a possible side reaction that could occur upon boiling in sulfuric acid?
PREPARATION OF PHARMACEUTICALS - Fischer Esterification Reactions Q: Calculate the expected mass of both methyl salicylate and aspirin assuming 100% yield. EXPERIMENT7 PREPARATION OF PHARMACEUTICALS Fischer Esterification Reactions Almost 2500 years ago, physicians such as Hippocrates recommended that patients chew on the bark of the willow to alleviate pain. The active ingredient in willow bark was found to be salicin, a compound made of a molecule of salicyl alcohol bonded to a p-D-glucose molecule. In the stomach, the bond between...
Methyl salicylate could be deacylated using sulfuric acid. What is a possible side reaction that could occur upon boiling in sulfuric acid?
Methyl salicylate could also be deacylated using sulfuric acid. What is a possible side reaction that could occur upon boiling in sulfuric acid?
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...
