Fischer esterification catalyst
WebGeneral Reaction: Fischer esterification (aka Fischer-Speier esterification and acid-catalyzed esterification) is a great way to take a carboxylic acid and convert it into an ester. All that’s required is a carboxylic acid, a strong acid catalyst, and an alcohol. Let’s go ahead and use acetic acid, H 3 O + (same as writing H + ), and ...
