Next is protonation of one of the alcohols again, followed by a loss of water.
The first step involves protonation of the carbonyl oxygen, followed by nucleophilic attack of the alcohol, finished off with a loss of a proton. Next is protonation of one of the alcohols again, followed by a loss of water. Finally electrons from the oxygen come down to form the double bond, and the loss of a proton yields the desired compound. FTP, name this reaction in which alcohols are reacted with carboxylic acids to give esters.
