Maleic anhydride

Maleic anhydride 25kg, wholesale is an organic compound. In its pure state, it is a colorless or white solid. It has a pungent odor, consists of diamond-shaped crystals. When interacting with water, it dissolves, transforming into maleic acid, when heated to 200 ° C - into fumaric acid. When interacting with alcohols, partial esters are formed. Maleic anhydride is obtained by the oxidation of benzene, or other aromatic compounds. In order to save money, many industries use n-butane 2 CH3CH2CH2CH3 + 7 O2 → 2 C2H2(CO)2O + 8 H2O to produce maleic anhydride for raw materials. Maleic anhydride, due to its high reactivity and the presence of two functional groups, has different chemical properties. Maleic anhydride is also used to produce tetrahydrofuran.

The chemical formula is C4H2O3.

Where is it applied?

For the production of tetrahydrofuran (THF), tetrahydrophthalic anhydride, gammabutyrolactone, for the synthesis of maleic, fumaric and malic acids.

In the manufacture of polyester and alkyd resins, as a raw material. In the pharmaceutical industry, it is used in the manufacture of drugs.

Also in the purification of aromatic substances from sulfur and nitrogen compounds, in the manufacture of detergents, plasticizers, chemicals for agriculture, additives and stabilizers for fuels and oils.
