Properties and Structure of MA

Maleic anhydride (MA) is chemically 2,5-furandione, or c/5-butene-dioic anhydride. It is also known by other names such as toxilic anhydride, maleic

being an anhydride, is subject to hydrolysis to the acid on storage. Thus, to obtain a pure sample of MA, purification is necessary. It is purified commercially by distillation. In small-scale laboratory-type uses, MA can be purified by sublimation or crystallization. Its solubility in various solvents is given in Table Chloroform or aromatic solvents such as benzene,
