    Jul 21, 2008· However, the dicarboxylic acid has a much higher melting point than the anhydride, so this unknown impurity in the first product must have a lower melting point than 100 0 C. The other possibility could be the unreacted 3-sulfolene or maleic anhydride, which have a lower melting point than the anhydride product.

    Dogs were fed 60 mg/kg/day maleic anhydride for 990 days. The plasma levels of maleic anhydride were determined. An uptake rate constant of 3.49X10-3/day and an elimination rate constant of 8.32X10-2/day were calculated assuming a one compartment model. According to the model 99% of steady state was reached by day 55 of the study.

    maleic anhydride - an overview | ScienceDirect Topics

    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 required to purify and reform the remaining maleic anhydride.

    Material Safety Data Sheet Maleic anhydride

    Environmental: Maleic anhydride's fate in soil is unknown. Since it biodegrades in sewage treatment plants and hydrolyzes, it's likely that it will degrade in soil. A combination of these processes should be important. Maleic anhydride released into water will hydrolyze rapidly (half-life 0.37 min) to maleic acid.
