There are a number of smaller applications for maleic anhydride.

The maleate ion is the ionized form of maleic acid.

A better route to this otherwise esoteric compound starts with the maleic hydrazide.

The reaction with maleic anhydride gave only diethyl-1-ethoxynaphthalene-2,3-dicarboxylic acid anhydride.

Both maleic anhydride and vinyl-silane modified polymers are being studied.

It is through this reaction that maleic anhydride converted to many pesticides and pharmaceuticals.

For instance, with maleic acid and with azobenzene, often by photoisomerization.

Maleic acid is more soluble in water than fumaric acid.

Some producers spray their crop with maleic hydrazide, which suppresses the shoots.

The food industry uses maleic anhydride in artificial sweeteners and flavour enhancements.

Maleic anhydride is a low hazard profile chemical.

About 10% of maleic anhydride is also produced:

Ozonolysis of maleic acid is also effective.

Maleic anhydride is produced by the oxidation of benzene or butane.

Maleic acid is a less stable molecule than fumaric acid.

The major industrial use of maleic acid is its conversion to fumaric acid.

Maleic anhydride's largest use today is in the production of unsaturated polyester resins.

It is the acid anhydride of maleic acid.

Instead, most maleic anhydride is produced by vapor-phase oxidation of n-butane.

Personal care products consuming maleic anhydride include hair sprays, adhesives and floor polishes.

Solid maleic anhydride pastilles are transported by transport trucks.

Maleic anhydride is a skin and respiratory sensitizer.

An example case is maleic anhydride and styrene, with reactivity ratios:

These compounds are catalysts for the oxidation of butane to maleic anhydride.

Maleic acid esters are also called maleates, for instance dimethyl maleate.
