ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Maleic anhydride was traditionally manufactured by the oxidation of benzene or other aromatic compounds. Maleic anhydride is an organic compound with the formula C2H2(CO)2O. Data on corresponding solid–liquid equilibrium of maleic anhydride in different organic solvents are essential for industrial design and further theoretical studies. Application Maleic anhydride may be used in the synthesis of unsaturated polyester resins and as a reactant in synthesizing important products such as agricultural chemicals, lubricant additives and food acidulatents. , maleic anhydride is collected and derivatized on p-anisidine-coated XAD-2 tubes. 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. Results of these measurements were well-correlated with the modified … 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. Methylene Dichloride. The experimental data and model parameters would be useful for optimizing the process of purification of maleic anhydride in industry. In those experimental conditions, the organic peroxide undergoes an homolytic rupture and carries out a polypropylene tertiary hydrogen abstraction. An improved process for recovery of maleic anhydride by using organic solvent Download PDF Info Publication number EP2595974B1. Several concentrations of maleic anhydride and organic peroxide were used for this study. For the temperature range investigated, the solubilities of maleic anhydride in the organic solvents increased with increasing temperature. 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. Maleic anhydride is a classic substrate for Diels-Alder reactions. Maleic anhydride is very soluble in water and readily reacts with water to form maleic acid.
