Application
Maleic acid has been used in the preparation of tris-maleate buffer[6] and sodium maleate buffer.[7][8] It has also been used for the pretreatment of poplar tracheid cell walls for the spectroscopic analysis of lignin.[1] It may be used to synthesize superswelling acrylamide/maleic acid hydrogels.[9]
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.[2] Its crystalline structure has been analyzed.[3] Reaction kinetics and mechanism of the isomerization of maleic acid to fumaric acid in the presence of ceric and bromide ions has been investigated.[4] The reaction mechanism and reactivity ratios for the radical copolymerization of maleic acid with styrene have been determined.[5]
