Benzoquinonetetracarboxylic dianhydride is an organic compound with formula C
8 (an oxide of carbon) which can be seen as the result of removing two molecules of water H
2O from benzoquinonetetracarboxylic acid.
It is a red solid, stable in dry air up to 140 °C, insoluble in ether, carbon tetrachloride, dichloromethane, carbon disulphide. It reacts with acetone, ethyl acetate, tetrahydrofuran, ethanol, and water. It dissolves in methylated derivatives of benzene to give solutions ranging from orange to violet. When the molecule is exposed to moist air it quickly turns blue.
