Maleic anhydride was traditionally manufactured by the oxidation of benzene or other aromatic compounds. The calculated solubilities showed good agreement with the experimental data. The patent teaches that, thanks to the great solubility of maleic anhydride in, the solvent even at low temperature, the maleic anhydride can be recovered in a column using DBP as absorption medium even at moderate conditions of temperature and pressure. 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%. I am Interested. Ì Explore More Product. NO IT WILL NOT DISSOLVE IN ORGANICS Actually, maleic acid [CAS#110-16-7] does have some organic solubility. It was used for work in 1928, on the reaction between maleic anhydride and 1,3-butadiene, for which Otto Paul Hermann Diels and Kurt Alder were awarded the Nobel Prize in 1950. 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. 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. The relation between solubility and crystal size formation has also been studied. 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. 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.

Data on corresponding solid–liquid equilibrium of maleic anhydride in different organic solvents are essential for industrial design and further theoretical studies. , maleic anhydride is collected and derivatized on p-anisidine-coated XAD-2 tubes. One can dissolve >100mg per 1mL in isopropanol (IPA) and tetrahydrofuran (THF). It is the acid anhydride of maleic acid and in its pure state is a colorless or white solid with an acrid odor. The solubility of maleic anhydride in those mixed solvents increased with increasing temperature, but the rate of solubility is different. ˆ&. In those experimental conditions, the organic peroxide undergoes an homolytic rupture and carries out a polypropylene tertiary hydrogen abstraction. This preference, however, changes in favor of the exo‐isomer on inclusion of solvent effects. EXPOSURE: Workers handling maleic anhydride in manufacturing may breathe in vapors or have direct skin contact. The solubility of sirolimus drug in different organic solvents, viz., acetone, chloroform, methanol, ethanol, and dichloromethane, has been measured for the temperature range of (295 to 345) K by a gravimetric method. Treatment with maleic anhydride had no effect on litter size or on pup survival at doses up to 150 mg/kg/day in the F1a and F1b litters and at doses up to 55 mg/kg/day in the F2a and F2b litters.
