WebJul 12, 2016 · Supported iron oxide nanoparticles on mesoporous materials (FeNP@SBA-15) have been successfully utilized in the esterification of a variety carboxylic acids including aromatic, aliphatic, and long-chain carboxylic acids under convenient reaction conditions. The supported catalyst could be easily recovered after reaction completion … The primary advantages of Fischer esterification compared to other esterification processes are based on its relative simplicity. Straightforward acidic conditions can be used if acid-sensitive functional groups are not an issue; sulfuric acid can be used; weaker acids can be used with a tradeoff of longer reaction times. Because the reagents used are "direct," there is less environmental impact in terms of waste products and harmfulness of the reagents. Alkyl halide…

Fischer–Speier esterification - Wikipedia

WebThe mechanism for ester hydrolysis is the reverse of the mechanism of Fischer esterification. There's usually no strong enthalpic favoring for one side of the reaction or the other, because water and alcohol are roughly equally poor nucleophiles and poor leaving groups, and the strengths of the bonds being made and being broken are similar. WebJan 8, 2024 · Fischer esterification is an acid-catalyzed condensation of a carboxylic acid with an alcohol to form esters. This is a reversible reaction, and it is carried out in the presence of concentrated acids such as sulphuric acid (H 2 SO 4).This reaction was discovered by Emil Fisher and Arthur Speier in 1895.
