The Fischer esterification is an organic reaction between a carboxylic acid and an alcohol to form an ester. Esters contribute to a wide variety of relevant molecules from flavors and fragrances to pharmaceuticals. The current reaction conditions use corrosive catalysts, require long reaction times, and generate excess chemical waste. Recently, a series of ionic compounds derived from nicotinic acid have been synthesized. Nicotinic acid, or vitamin B3, is an essential nutrient in the human body. When chemically modified, these ionic compounds could serve as alternative catalysts for the Fischer esterification and the potential exists to develop a more efficient and environmentally friendly chemical process. The synthesis, optimization, and catalyst recycling studies show promising results, with possible future applications in organic synthesis.
