    Does fumaric acid form stronger hydrogen bonds than maleic .

    What your book (probably) meant is that the hydrogen bonds in fumaric acid, being inter molecular, does a better job of holding the molecules together, so it has a higher boiling point than maleic acid, which instead, displays intra molecular hydrogen bonding which doesn't hold …

    Maleic anhydride CAS#: 108-31-6

    Maleic anhydride (butenedioic anhydride, toxilic anhydride, 2,5- dioxofuran ) is an organic compound with the formula C 2 H 2 (CO) 2 O. It is the acid anhydride of maleic acid and in its pure state it is a colourless or white solid with an acrid odour. Chemical Properties: Maleic anhydride is colorless needles, white lumps, or pellets.

    Maleic Anhydride - an overview | ScienceDirect Topics

    The vapor mixture leaving the reactor is cooled down to 55°C by heat exchangers, and 40–60% of the maleic anhydride is recovered as liquid. Contact of maleic anhydride with water results in the undesired formation of maleic acid. The maleic anhydride that cannot be recovered is eventually washed out with water as maleic acid. Water scrubbing and subsequent dehydration of the maleic acid stream are …
