Question
Methyl anthranilate is an ester found in grape juice. It can be prepared synthetically by esterification of anthranilic acid according to the reaction below. You decide to synthesize this in your lab by adding methanol in the presence of acid. After you have run the reaction and have cooled it, you begin the work-up by neutralizing the acid with 5% sodium bicarbonate. You observe the white compound in your reaction flask begins to dissolve in the aqueous solution. Is this a sign that you have, or do not have, the expected product? Use chemical structures and words to explain your answer.Explanation / Answer
during acidic condition when methanol is added into the reaction at hot condition the esterification reaction taking place with removal of water molecules from the rection. when we try to quench the reaction ,acid get neutralise with formation of salt ,which is soluble into aqueous solution but the generated ester is present in to the reaction mass ,to remove our expected product we have to extract it from reaction mass using ethyl acetate or dichloro methane.and then concentrate that organic layer. we recive desire product
