0000002210 00000 n %%EOF Essentially, we are drawing the reverse order of Fischer esterification so, in the first step the ester is protonated promoting the nucleophilic attack of water: Notice that just like the Fischer esterification, the process is an equilibrium which makes the reaction a little challenging as it may require higher temperatures and removal of the alcohol as it is formed to push the equilibrium forward. This is a common mechanism in organic chemistry, and its mastery is important in learning how carbonyl compounds behave. hA 0000006684 00000 n 0000012873 00000 n 0000011949 00000 n draw the organic product formed in the following reaction.

Draw the structure of the major organic product formed in the reaction. So if you start with the carboxylic acid, and you add an alcohol, and a source of protons, you're gonna form your ester, and you're also going to make water in this process. It was observed that 5% Ru/C was an active catalyst for hydrogenation of both aromatic ring and carboxylic group, while Pd/C catalyst hydrogenated only aromatic ring. Step 2: Preparation of ethyl p-aminobenzoate (esterification of p-aminobenzoic acid) Place 80 ml of absolute ethanol in a 250 ml two-necked flask equipped with a double surface reflux condenser and a gas inlet tube.
