词源

Etymology tree German Benzoe German -in German Benzinbor. English benzine English benzene A technical term in chemistry, adopted in English in 1835 as benzine (benzene from 1872), from German Benzin, which was coined in 1833 by Eilhardt Mitscherlich based on Benzoesäure (“benzoic acid”), plus the technical ending -ene (German -in) denoting hydrocarbons. The adjective benzoic is in turn from benzoin, originally a term for a balsamic resin from Middle French benjoin, from Spanish benjuí, Portuguese beijoim, Italian benzoe, probably, from Arabic لُبَان جَاوِيّ (lubān jāwiyy, “Javanese frankincense”). Not related to German Benz (surname).
