OLEFINE See also:TERPENES Myrcene, C,oHic, was first isolated by F. B. See also:Power and C. Klebet from oil of See also:bay (See also:Schimmel & Co., Bulletin, See also:April 1895, p. II); it is also found in oil of sassafras leaves. It is obtained from bay oil by shaking the oil with a 5 per cent. See also:solution of See also:caustic soda, followed by fractionation in vacuo. It boils at 67-68° C. (20 mrn.), and polymerizes when heated for some See also:time. When oxidized by See also:potassium permanganate it yields succinic See also:acid. By the See also:action of glacial acetic acid in the presence of dilute sulphuric acid, a liquid is produced, which on See also:hydrolysis yields myrcenol, C,oH,30, an See also:alcohol which is probably an isomer of linalool (P. See also:Barbier, See also:Corn pies rendus, 1901, 132, p. 1048). The See also:hydrocarbon is probably to be considered as being (See also:CH3)2C : CH . (See also:CH2)2 . C(: CH2) . CH : CH2 (Enklaar, Bulletin of Rouse-See also:Bertrand fits, Nov., 1906, p. 92). Ocymene is an isomer which can be extracted from the leaves of the See also:basil. Enklaar (loc. cit.) represents it as (CH3)2C: CH . CH2 . CH : C(CH3) • CH : CH2. Anhydro-geraniol, C,oHls, the first olefine terpene isolated, was pre; pared in 1891 by F. W. Semmler; it is formed when geraniol is heated with potassium bisulphate to 170`' C. Additional information and CommentsThere are no comments yet for this article.
