Kind Code: A1 . 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. Maleic anhydride is very soluble in water and readily reacts with water to form maleic acid. We use cookies to help provide and enhance our service and tailor content and ads. In those experimental conditions, the organic peroxide undergoes an homolytic rupture and carries out a polypropylene tertiary hydrogen abstraction. 2013-03-08 11:32:34.

Copyright © 2020 Elsevier B.V. or its licensors or contributors. 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. Solubility ( solvents ) Soluble in common organic solvents ( alcohol, ether, petroleum ether, dioxane, DMSO, benzene and chloroform ) Boiling point °C at 101.3 kPa 202 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. Display Name: Maleic anhydride EC Number: 203-571-6 EC Name: Maleic anhydride CAS Number: 108-31-6 Molecular formula: C4H2O3 IUPAC Name: 2,5-dihydrofuran-2,5-dione United States Patent Application 20130150594 . It is the acid anhydride of maleic acid and in its pure state is a colorless or white solid with an acrid odor. Ì Maleic anhydride is an organic compound with the formula C2H2(CO)2O. [1]. I am Interested. Data on corresponding solid–liquid equilibrium of maleic anhydride in different organic solvents are essential for industrial design and further theoretical studies. 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%. à Measurement and correlation of the solubility of maleic anhydride in different organic solvents. X. Results of these measurements were well-correlated with the modified Apelblat equation, the Buchowski–Ksiazaczak λh equation and the van’t Hoff equation. Abstract: A process for the recovery of maleic anhydride from the gas produced by the catalytic oxidation of hydrocarbon, n-butane or benzene, is characterized by: a) High efficiency in maleic anhydride recovery; b) Reduced formation of maleic acid … Of these measurements were well-correlated with the formula C2H2 ( CO ) 2O Elsevier B.V organic solvent can >!
