The surface-enhanced Raman scattering (SERS) spectra of maleic (cis; 2-butaneoic acid) and fumaric (trans; 2-butaneoic acid) acids adsorbed on aqueous silver sol particles are reported. These two acids form two groups of isomers which differ only in the relative positions of the two ...
Allergic contact dermatitis from esters of fumaric acid or esters of maleic acid is rare. The case of a chemist with allergic reactions to esters both of fumaric acid and of maleic acid is presented. Extremely high sensitivity of the patient to diethyl fumarate was noted. The formation of iden...
Fumaric acid is the trans and maleic acid the cis isomer. The physical properties of maleic acid and fumaric acid are very different. The cis isomer is less stable. Maleic acid is used in the preparation of fumaric acid by catalytic isomerization. Physical properties Maleic acid is a less ...
Since the early '40s, and through most of the '60s, fumaric acid was industrially obtained from the mould Rhizopus arrhizus; its fermentative production, however, has long been abandoned for economic reasons. At present time, in fact, this acid is commercially obtained by chemical synthesis via...
Chemical Industry: In the chemical industry, maleic acid is used as a precursor for the production of various chemicals, such as fumaric acid, maleic anhydride, and succinic acid. It serves as a building block for the synthesis of polymers, resins, and pharmaceuticals. Food Industry: Maleic aci...
The conversion from fumaric acid to maleic acid can be done by hydrolytic conversion. The fumarase may catalyze this reaction with the help of a liquid membrane. Answer and Explanation:1 Usually, fumaric and malic acids are the geometrical isomers, which means the molecular f...
The Diels-Alder Reactions of the Piperylene Isomers with Maleic Anhydride and Fumaric Acid 1. The well-known maleic anhydride adduct of trans-piperylene, m. p. 63°, was found to have the cis,cis,cis configuration. 2. The two trans anhydride isomers, m. p. 121° and 133°, were both...

A combination of maleic acid and sodium hypophosphite as a durable press finishing agent has been reported as a safer but equally effective alternative to conventional formaldehyde-based cross-linking agents for applications in cellulose-based fiber and textile finishing. However, the mechanistic details...
