Ethylenetetracarboxylic dianhydride is a chemical compound with formula C
6O
6, that can be seen as the twofold anhydride of ethylenetetracarboxylic acid C
6H
4O
8. Its molecular backbone consists of two five-atom dihydrofuran-like rings, each containing one oxygen atom and four carbon atoms, sharing a pair of carbons. It is one of the oxides of carbon.
The compound and its reactions were studied in 1967 by Sauer, Schröder and others.[1][2] Synthesis of the compound by pyrolysis of ethylenetetracarboxilic acid was reported in 1981 by Patterson and others.[3]
The compound was also obtained in 2009 by Taherpour, by microwave pyrolysis of solid Meldrum's acid.[4] The compound yields a pale yellow solution in dichloromethane.[4]
