Acid anhydride (original) (raw)
Säureanhydride (meist nur Anhydride genannt) ist die Bezeichnung für eine Gruppe chemischer Verbindungen, die immer Derivate sauerstoffhaltiger Säuren sind. Sie entstehen formal durch Abspaltung von Wasser (Dehydratisierung) aus einer Säure. Aus anorganischen Sauerstoffsäuren bilden sich Oxide, wie z. B. aus Phosphorsäure Phosphorpentoxid. Aus den organischen Carbonsäuren bilden sich so genannte Carbonsäureanhydride.

In organic chemistry, organic acid anhydrides contain the functional group R(CO)O(CO)R'. Organic acid anhydrides often form when one equivalent of water is removed from two equivalents of an organic acid in a dehydration reaction. In inorganic chemistry, an acid anhydride refers to an acidic oxide, an oxide that reacts with water to form an oxyacid (an inorganic acid that contains oxygen or carbonic acid), or with a base to form a salt.
