rhodinol Chem.|ˈrəʊdɪnɒl|
[a. G. rhodinol (U. Eckart 1891, in Arch. d. Pharm. CCXXIX. 364), f. Gr. ῥόδῐν-ος of or from roses (f. ῥόδον rose): see -ol.]
An open-chain terpenoid primary alcohol, C10H20O, which is a red liquid first isolated from rose oil, and now known to be a mixture of two isomeric forms and to be identical with citronellol except in respect of the relative proportions of the isomers.
1892Jrnl. Chem. Soc. LXII. i. 203 The author proposes the name rhodinol for the compound. 1894Ibid. LXVI. i. 141 When oil of pelargonium is subjected to careful fractional distillation under reduced pressure, it yields rhodinol,..identical..with the rhodinol obtained from oil of roses. 1929[see menthone]. 1953D. H. R. Barton in E. H. Rodd Chem. Carbon Compounds IIb. xii. 496 The question of the constitution of citronellol and rhodinol is still a matter of controversy. 1956I. L. Finar Org. Chem. II. viii. 265 Rhodinol is identical with citronellol, but the proportions of the two forms are different from those which occur in citronellol; the identity of citronellol and rhodinol is shown by the products of ozonolysis. 1959P. de Mayo Mono- & Sesquiterpenoids i. 40 Rhodinol, isolated from rose oil, was for a long time considered to be distinct from citronellol, but it would appear that pure rhodinol and pure citronellol are identical.
Hence ˈrhodinal [a. G. rhodinal (op. cit., p. 373): see -al2], the aldehyde, C10H18O, which is obtained by oxidation of rhodinol and is an analogous mixture of isomers resembling citronellal.
1900Jrnl. Chem. Soc. LXXVIII. i. 452 Analyses are quoted in further proof of the isomeric change of rhodinal into menthone. 1929[see hydroxycitronellal s.v. hydroxy- 3]. 1951A. W. Johnson et al. in E. H. Rodd Chem. Carbon Compounds Ia. viii. 504 Citronellal and its isomer rhodinal are olefinic aldehydes. 1956I. L. Finar Org. Chem. II. viii. 265 A detailed study of rhodinal has shown that this compound is identical with citronellal, but consists of a mixture of the two forms in different proportions. |
