The solubility of terpolymers containing alkyl, and perfluoroalkyl side chains as well as succinic acid moieties in the main chain, P[R F MA 0.2-co-R H MA 0.65-co-MAH 0.15] (R H = C₄H₉- or C 12 H 25-, R F - = C 10 H₄F 19-) with ca. Keywords: Maleic anhydride copolymers, Chemical modification, DMTA, T g, MAN, Phthalimide Background Maleic anhydride (MAN) is an excellent monomer which can provide reactive anhydride or carboxylic groups with nucleophilic molecules, as discussed by Zhou et al. Subsequently the maleic anhydride is removed from the solvent by stripping under vacuum conditions and elevated temperature. Acetonitrile Solvent. Copyright © 2014 Elsevier B.V. All rights reserved. X. PROCESS FOR RECOVERY OF MALEIC ANHYDRIDE BY USING ORGANIC SOLVENT . In those experimental conditions, the organic peroxide undergoes an homolytic rupture and carries out a polypropylene tertiary hydrogen abstraction. à 20 mol % fluorinated side chains and 10⁻22 mol % of succinic anhydride rings was tested in a number of solvents varying from water to non polar mineral oils. The resulting macroradical undergoes a β‐scission leading to a radical chain end which reacts with maleic anhydride. In this study, the solubilities of maleic anhydride were measured in DMF, methanol, acetic acid, acetonitrile, acetone, ethyl acetate, 2-propanol and n-butyl alcohol with the temperature range of 278.15–323.15 K by the analytical stirred-flask method under atmospheric pressure. Solubility of maleic anhydride in methanol + (acetone, ethyl acetate) from 278.15 to 323.15 K The chemistry of maleic anhydride is very rich, reflecting its ready availability and bifunctional reactivity. The experiment results indicated that the solubility of maleic anhydride was highest in DMF and followed by methanol, acetic acid, acetonitrile, acetone, ethyl acetate, 2-propanol and n-butyl alcohol. Xylene. Addition of an organic co-solvent generated a biphasic system, and improved the selectivity to maleic acid (up to 61% in the case of tetrachloroethane) with a concomitant reduction of the furfural conversion in most cases. The experiment results indicated that the solubility of maleic anhydride was highest in DMF and followed by methanol, acetic acid, acetonitrile, acetone, ethyl acetate, 2-propanol and n-butyl alcohol. This colorless solid is the acid anhydride of succinic acid Preparation In … endobj The solubility of succinic anhydride in acetone, acetonitrile, 2-propanol, ethyl acetate, acetonitrile + ethyl acetate, acetone + ethyl acetate was determined with temperature range from 278.15 to 333.15 K under atmospheric pressure using the analytical stirred-flask method. The modified Apelblat equation was found to regress the solubility data is higher accuracy than the Buchowski–Ksiazaczak λh equation. Ì Data on corresponding solid–liquid equilibrium of maleic anhydride in different organic solvents are essential for industrial design and further theoretical studies.

With our expertise and trustworthiness, we are engaged in offering an optimum quality range of Maleic Anhydride. Asked by Wiki User. It is the acid anhydride of maleic acid. Eng. Maleic anhydride is very soluble in water and readily reacts with water to form maleic acid. In this study, the solubilities of maleic anhydride were measured in DMF, methanol, acetic acid, acetonitrile, acetone, ethyl acetate, 2-propanol Ì Solubility ( solvents ) Soluble in common organic solvents ( alcohol, ether, petroleum ether, dioxane, DMSO, benzene and chloroform ) Boiling point °C at 101.3 kPa 202 I would not do so on a flask of hexanes.
