Brit.

/ɔˌtɑksəˈdeɪʃ(ə)n/,

/ɑˌtɑksəˈdeɪʃ(ə)n/

Forms:

α. 1800s– autoxidation.

β. 1800s– auto-oxidation.

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: auto- comb. form¹, oxidation n.

Etymology: < auto- comb. form¹ + oxidation n., after German Autoxydation (M. Traube 1883, in Berichte der Deutsch. Chem. Ges. 16 126; now usually Autoxidation).

Chemistry.

Oxidation of a compound by spontaneous combination with oxygen under ordinary conditions of temperature and pressure; a reaction in which this occurs.
