Maleic anhydride which is a dihydro- furan shows initially a single wave at a potential considerably more positive than the reduction potential of diethyl maleate; with time a second maleic anhydride wave appears and grows at the expense of the first wave

Is maleic anhydride an acid or a derivative?

Maleic anhydride is the derivative of an acid (maleic acid), and the hydrolysis of maleic anhydride gives an acid (maleic acid). However, maleic anhydride itself is not an acid. Is maleic anhydride a hazard?

How is maleic acid produced?

In industry, maleic acid is derived by hydrolysis of maleic anhydride, the latter being produced by oxidation of benzene or butane. Maleic acid is an industrial raw material for the production of glyoxylic acid by ozonolysis.

Which reaction is used for maleic anhydride production?

The process using n -butane as the starting molecule is, however, nowadays the only industrially used reaction for maleic anhydride production ( Fernández et al., 2010; Chen et al., 2007; Gascón et al., 2006; Ivars et al., 2010; Ozkan et al., 1997 ).

What is maleic anhydride used for?

These resins happen to be the major end use of maleic anhydride as feedstock in its production. These laminating resins, which have high structural strength and good dielectric properties are used both in glass-reinforced and inunreinforced applications.
