CH2 CH = CH CH2 -- CH =CH CH2•CH2CH ,a -'See also:des-methyl cyclo-octadiene granatanine Cyclo-octadiene, CSH12, as above prepared, is a strong-smelling oil which decolorizes See also:potassium permanganate See also: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, See also: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 See also:hydrocarbon by the See also:Sabatier and Senderens's method. It is a liquid which boils at 146.3-148° C. and possesses a strong camphor odour. On oxidation it yields suberic See also:acid (R.

Willstatter, Ber., 1907, 40, pp. 957). O. Doebner (See also:

Bee., 1902, 35, pp. 2129, 2538; 1903, 36, p. 4318) obtained compounds, which in all See also:probability are cyclo-octadienes, by the See also:distillation of p-vinylacrylic acid, sorbic .acid, and cinnamenyl acrylic acid with anhydrous baryta. Cyclo-nonane See also: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 See also:lime, and from this, by reduction to the corresponding secondary See also:alcohol, See also:conversion of the latter into the iodide, and subsequent reduction of this with See also:zinc, cyclo-nonane, C,H18, a liquid boiling at 170-172° C. is obtained.
