Maleic anhydride is readily hydrolyzed to maleic acid under aqueous conditions. Chemsrc provides Maleic acid(CAS#:110-16-7) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. IDENTIFICATION: Maleic anhydride appears as colorless needles or white lumps or pellets.

Uses As a result, these two chemicals are presented because of the conditions used to test their toxicity. Its chemical formula is HO 2 CCH=CHCO 2 H. Maleic acid is the cis-isomer of butenedioic acid, whereas fumaric acid is the trans-isomer.It is mainly used as a precursor to fumaric acid, and relative to its parent maleic anhydride, maleic acid has few applications. The key difference between maleic acid and fumaric acid is that maleic acid is the cis-isomer of butenedioic acid, whereas fumaric acid is the trans-isomer. This article presents a simple laboratory experiment that is designed to enhance students' understanding of inter- and intramolecular hydrogen bonding by demonstrating the comparative effect of these phenomena on some chemical and physical properties.
OSHA Vacated PELs: Maleic acid: No OSHA Vacated PELs are listed for this chemical.

Explain why maleic and fumaric acids have very different melting points? It is used to make other chemicals and for dyeing and finishing naturally occurring fibers. It is combustible though it may take some effort to ignite. From Wikipedia. Both properties of maleic acid can be explained on account of the intramolecular hydrogen bonding [1] that takes place at the expense of intermolecular interactions. Sigma-Aldrich offers a number of Maleic acid products.

... Poly(styrene-alt-maleic acid) sodium salt solution.

Malic acid melts at 130 degrees C. It doesn't really boil, but it will decompose instead at 140 degrees C to produce carbon monoxide, carbon dioxide, maleic acid and maleic anhydride. Articles of Maleic acid are included as well. Personal Protective Equipment Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in … Fumaric acid can form intermolecular hydrogen bonds (strong) while maleic acid forms intramolecular hydrogen bonds (weak), hence fumaric acid has higher boiling point than maleic acid."

Anmol Chemicals is the pioneer manufacturers of Maleic Acid, Pharmaceutical Excipients Fragrance & Flavor chemicals in India.We offer Halal and Kosher Maleic Acid made in an ISO9001, ISO22000 (FSSC22000) and cGMP certified facility. Moreover, maleic acid forms weak intramolecular hydrogen bonds and has a much lower melting point than fumaric acid. ...
