Origin: Formed within English, by compounding; modelled on a French lexical item. Etymons: acetic adj., naphthene n.

Etymology: < ace- (in acetic adj.) + naphthene n., after French acénaphtène (M. Berthelot 1867, in Bull. de la Soc. Chim. de Paris 7 278).

Chemistry.

A crystalline aromatic hydrocarbon found in coal tar and used in the manufacture of dyes and pesticides.Acenaphthene has a tricyclic molecule similar to that of acenaphthylene except that the ethylene bridging group is saturated. Systematic name: 1,2-dihydroacenaphthylene; C₁₂H₁₀.
