Product Description

Product Description

Synonym: 2.5-Furandione, cis-butene-dioic anhydride
Molecular Formula: C4H2O3
Molecular Weight: 98.058
CAS No.: 108-31-6
Property: It is a kind of white briquettes with heavy irritant oder. Sp. gr. (solid) 1.48, m. p, 52.8°C, b.p200°C (760mmHg), also
readily sublimates. soluble in water, forming maleic acid.

Used mainly for synthesizing unsaturated polyester resins, coatings, pharmaceutics, pesticides, lubricating oil additives,
foodstuff additives etc.
At room temperature, it is a white flaky crystal with irritant odour and sour, inflammable and sublimating. It can be freely
dissolved in water to form maleic acid. It has a specific density of 1.480, a melting point of 52.85 °C, and a boiling point of
202°C.

Storage:
