DESCRIPTION General description Maleic acid (MA) is a dicarboxylic acid that undergoes esterification with ethanol in the presence of cation-exchange resin catalysts to form diethyl maleate.[1] Its crystalline structure has been analyzed.[2] Reaction kinetics and mechanism of the isomerization of maleic acid to fumaric acid in the presence of ceric and bromide ions has been investigated.[3] The reaction mechanism and reactivity ratios for the radical copolymerization of maleic acid with styrene have been determined.[4] Application Maleic acid has been used in the preparation of tris-maleate buffer[5] and sodium maleate buffer.[6][7] It has also been used for the pretreatment of poplar tracheid cell walls for the spectroscopic analysis of lignin.[8] It may be used to synthesize superswelling acrylamide/maleic acid hydrogels.[9] Quality Repurified Legal Information ReagentPlus is a registered trademark of Merck KGaA, Darmstadt, Germany |
