† retinaphthan.

Forms:

α. 1800s rétinnapthe.

β. 1800s retinaphtha.

Origin: Of multiple origins. Partly a borrowing from French. Partly a borrowing from Greek, combined with an English element; modelled on a French lexical item. Etymons: French rétinnapthe ; Greek ῥητίνη , naphtha n.

Etymology: In α. forms < French rétinnapthe (see below); in β. forms < retin- (in ancient Greek ῥητίνη resin: see retinite n.) + naphtha n., after French rétinnapthe (P. J. Pelletier & J. Walter 1837, in L'Institut: Sci. math., physiques et nat. 5 190/2). Compare retinol n.¹ N.E.D. (1908) gives the pronunciation as (retinæ·fþă) /rɛtɪˈnæfθə/.

Chemistry. Obsolete.

A hydrocarbon obtained by distilling pine resin, now regarded as identical with toluene.

1857 W. A. Miller Elements Chem.: Org. (1862) 655 Toluol, or benzoene,..appears to be identical with the retinaphtha obtained by Pelletier..from the distillation of rosin.

1888 H. E. Roscoe & C. Schorlemmer Treat. Chem. III. 4 Deville..considered, nevertheless, that benzoene was not identical, but isomeric with retinaphtha.
