idryln.

1845 C. Bödeker in Chem. Gaz. 15 Feb. 73 One of the products obtained in the working of the bituminous mercurial ores in Idria is the so-called Stupp, a soft black mass mixed with globules of mercury. It was supposed to contain idrialine, but in its stead another hydrocarbon was found, idryle C³H, and a more accurate examination has proved that idrialine..is an oxide of idryle.

1863 Fownes's Man. Elem. Chem. (ed. 9) 698 Idrialin..is generally associated with a hydrocarbon idryl.

1866 H. Watts tr. L. Gmelin Hand-bk. Chem. XVII. 477 Idryl. C⁴²H¹⁴... The crystals are nearly colourless, with a tinge of yellowish-green... Idryl assumes a golden-yellow colour in cold oil of vitriol.

1877 Chem. News 16 Nov. 222/2 G. Goldschmidt, ‘Idryl’. This body, found by Bödeker in Idria, is ascertained to consist of several hydrocarbons... Besides chrysen, pyren, anthracen, phenanthren, a new hydrocarbon, C₁₅H₁₀, was isolated, and receives the name originally applied to the mixture.

1892 H. E. Roscoe & C. Schorlemmer Treat. Chem. (new ed.) III. vi. 523 Fluoranthene, C₁₅H₁₀, is found in coal-tar, and is also identical with idryl, one of the constituents of ‘stuppfett’.

1926 H. G. Rule tr. J. Schmidt Text-bk. Org. Chem. ii. xvii. 513 Fluoranthene or Idryl, m.p. 110°, b.p. 250° (at 60 mm.).

1952 Chem. Rev. 50 483 In 1844 Boedeker..distilled these ores, with production of a similar hydrocarbon which he named idryl. Much later Goldschmiedt..showed..that idryl consisted of anthracene, phenanthrene, chrysene, pyrene, and a hitherto unknown hydrocarbon, C₁₅H₁₀, to which he gave the name idryl. Simultaneously with Goldschmiedt's discovery, Fittig and Gebhard..isolated..a hydrocarbon which was named fluoranthene and was claimed to be identical with Goldschmiedt's idryl.
