15. Alex is synthesizing wintergreen oil (methyl salicylate) by sulfuric acid catalyzed esterification of salicylic acid with methanol using a 1:1 mol ratio of acid and alcohol. After refluxing the mixture and checking ¹H-NMR after 45 minutes, 4 hours, and then again after 1 day, Alex finds that the ratio of alcohol, acid, ester, and water is 1:1:1:1 every time. Briefly describe how Alex could modify this procedure to achieve an equilibrium concentration with a larger fraction of product and lower fraction of reactant. tv MacBook Air W D
