Fischer esterification catalyst
WebJun 29, 2024 · 5 Concentrated sulfuric acid is often used as a catalyst in Fischer esterification reactions. To my knowledge, the role it plays in the reaction is not as a reducing agent or dehydrating agent but only serves the role of creating an acidic environment, as seen in the mechanism. Thus, dilute sulfuric acid would be sufficient. WebCommunity Catalyst is a national non-profit advocacy organization dedicated to quality affordable health care for all.
