Maleic anhydride
The synthesis methods of maleic anhydride mainly include benzene oxidation, butene oxidation, butane oxidation, etc. In the past, most of the production used benzene oxidation method, i.e. benzene is used as raw material and maleic anhydride is obtained by catalytic oxidation. However, due to the price, most of them use n-butane oxidation method to produce.
