It is produced industrially on a large scale for applications in coatings and polymers. Top Answer. X. Results of these measurements were well-correlated with the modified Apelblat equation, the Buchowski–Ksiazaczak λh equation and the van’t Hoff equation.

It is through this reaction that maleic anhydride converted to many pesticides and pharmaceuticals. Water Solubility: 79 g/100 mL : With our expertise ... With our expertise and trustworthiness, we are engaged in offering an optimum quality range of Maleic Anhydride. The solubility of phthalic anhydride was measured at 283–313 K under atmospheric pressure in ethyl acetate, n-propyl acetate, methyl acetate, acetone, 1,4-dioxane, n-hexane, n-butyl acetate, cyclohexane, and dichloromethane.The solubility of phthalic anhydride in all solvents increased with the increasing temperature. United States Patent Application 20130150594 . By continuing you agree to the use of cookies. Methylene Dichloride. Eng. Solubility of the copolymer products was tested in some organic solvents. Several concentrations of maleic anhydride and organic peroxide were used for this study. Yes! Ì à Without the organic co-solvent, the yield of maleic acid was 38.1% with 44.2% of selectivity, and the conversion of furfural was as high as 86.2%. This preference, however, changes in favor of the exo‐isomer on inclusion of solvent effects. The modified Apelblat equation was found to regress the solubility data is higher accuracy than the Buchowski–Ksiazaczak λh equation. In a typical combination of those two properties, SMA is available as a crystal clear granule that can be used in a wide variety of applications. PROCESS FOR RECOVERY OF MALEIC ANHYDRIDE BY USING ORGANIC SOLVENT . It is a colorless or white solid with an acrid odor. Subsequently the maleic anhydride is removed from the solvent by stripping under vacuum conditions and elevated temperature. I would not do so on a flask of hexanes. USE: Maleic anhydride is used to make other chemicals that are used in resins, dyes, drugs and agriculture. 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. NO IT WILL NOT DISSOLVE IN ORGANICS Actually, maleic acid [CAS#110-16-7] does have some organic solubility. For the temperature range investigated, the solubilities of maleic anhydride in the organic solvents increased with increasing temperature.

Exposure is unlikely in the general population. 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. Get Best Quote. 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.
