(əˈkɒnɪk)
[Short. f. aconitic.]
1. In aconic acid: A non-saturated monobasic acid of formula C5H4O4.
| 1877 Fownes Man. Chem. II. 355 By boiling with baryta-water, aconic acid is resolved into formic and succinic acids. |
2. In comb. a group of isomeric non-saturated bibasic acids of formula C5H6O4 = C3H4.2(CO2H), derived from aconitic acid by the loss of carbon dioxide in distillation. They are distinguished as citraconic, itaconic, mesaconic, and paraconic.
| 1877 Fownes Man. Chem. II. 353 Citraconic and itaconic acids are produced by the action of heat on citric acid. |
