Cyclodecanone has been obtained together with other products in the pyrolysis of the thorium or yttrium salts of nonanedioic acid.3 4 It has also been prepared by reduction of sebacoin with zinc and hydrochloric acid,6, 6 by dehydration of sebacoin fol-... [Pg.30]

TLC spots with marker reveal the presence of free fatty acids (FFA), diglyceride (DG), monoglyceride (MG) but negligible amount of TG. GCMS of fatty acid— methyl esters (FAME) from lion mane presented evidence for fatty acids ranging from C9-C24 (Figs. 5.3- 5.6). Low volatility molecules like nonanedioic acid (Fig. 5.3), tridecanoic acid (Fig. 5.4), 12-methyl tridecanoic acid were also present in lion hair lipids. In addition fatty acids such as myristic, pentadecanoic, palmitic, heptanoic, stearic and octadecenoic acids (Fig. 5.5) have also been detected. Erucic... [Pg.63]

The solvents utilized were all analytical grade reagents further purified by distillation. A-(3-Triethoxysilyl)-propanamine (APTES), nonanedioic acid monomethyl ester, 12-nitro-dodecanoic acid, octadecanoic acid, octadecylamine, and lithium iodide were Aldrich samples and were used as received. Silicon wafers were supplied by International Wafer Service, Palo Alto, CA. [Pg.265]

Similarly, azelaic acid (1.9-nonanedioic acid) is synthesized from oleic acid (9-octadecenoic acid) (Scheme 3) and heliatropine, which a widely used fragrance, can be produced starting from isosafrol (Scheme 4). [Pg.40]
