CH2 CH = CH CH2 -- CH =CH CH2CH2CH ,a -'des-methyl cyclo-octadiene granatanine Cyclo-octadiene, CSH12, as above prepared, is a strong-smelling oil which decolorizes potassium permanganate solution instantaneously. It readily polymerizes to a di-cyclo-octadiene and polymer (C8H12~ (R. Willstatter, Ber., 1905, 38, pp. 1975, 1984; G. Ciamician and P. Silber, Ber., 1893, 26, p. 2750; A. Piccinini, Gaza ., 1902, 32, I p. 260). i3-cyclo-octadiene has been prepared from methyl granatinine iodmethylate.Cyclo-octane, C3H18 is obtained by the reduction of the above unsaturated hydrocarbon by the Sabatier
probability are cyclo-octadienes, by the distillation
Cyclo-nonane Group
According to N. Zelinsky (Bee., 1907, 40, p. 780) cyclononanone, C9H16O, a liquid boiling at 95-97 C., is formed on distilling sebacic acid with lime , and from this, by reduction to the corresponding secondary alcohol
conversion of the latter into the iodide, and subsequent reduction of this with zinc
