Maleic anhydride is a vital organic chemical, widely used in industries such as plastics, dyes, and pharmaceuticals. Below, we introduce the production process technologies of maleic anhydride.
There are four common production processes for maleic anhydride: the phenoxypropanol method, the ethylene dehydrogenation method, the phthalic anhydride method, and the coal chemical method.
First is the phenoxypropanol method: This process involves reacting benzene with benzyl oxide to produce phenoxypropanol, which is then oxidized with air to yield maleic anhydride. Its advantages include low reaction temperature, easily accessible reactants, and high output.
Next is the ethylene dehydrogenation method: In this process, ethylene is dehydrogenated under the catalysis of tartaric acid to form acrolein; the acrolein is then subjected to denitrification and deoxygenation to obtain maleic anhydride. The benefits of this method are mild reaction conditions and the ability to use ethylene directly as a raw material.
The third method is the phthalic anhydride method: Here, phthalic anhydride is used as the raw material, and maleic anhydride is generated via oxygen oxidation and decarboxylation. This process is characterized by easily available raw materials and a simple production process.
Finally, the coal chemical method: This approach uses coal as the raw material, which is pyrolyzed at high temperatures to produce gas; subsequent oxidation and decarboxylation reactions then yield maleic anhydride. Its key advantage is that coal is a widely available resource, enabling efficient utilization of coal reserves.
