The catalytic performance of (VO) P O , which is the industrial catalyst for the oxidation of n-butane to maleic anhydride, was studied in relation to the preparation methods of the catalyst and the reaction conditions when using the catalyst. It was shown that the difference in the ...
Figure 8. Synthesis of maleic anhydride from n-butane. Maleic acid is manufactured by hydrolysis of maleic anhydride. There are, however, few applications for maleic acid, the major industrial use being the isomerization into fumaric acid.29 Fumaric acid occurs naturally in many plants and is nam...
Maleic anhydride is a potent dienophile in Diels-Alder reactions. It is also a ligand for low-valent metal complexes, examples being Pt(PPh3)2(MA) and Fe(CO)4(MA). Maleic anhydride dimerizes in a photochemical reaction to form cyclo butane tetra carboxylic dianhydride (CBTA). This compound...
production method the main production methods of maleic anhydride are benzene oxidation, butene oxidation and n-butane oxidation, but benzene oxidation is still the main method. 1. Benzene oxidation process Benzene undergoes oxidation reaction in a fixed bed under the action of a V-Mo-P-based cat...
