Reaktive GruppeAcids, Carboxylic
Reactivity ProfileA weak carboxylic acid. Neutralizes bases with the evolution of substantial amounts of heat to produce water plus a salt. Reacts with solutions of cyanides to cause the release of gaseous hydrogen cyanide. Can generate flammable and/or toxic gases and heat by reaction with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. Reacts in with aqueous solutions of nitrites and thiosulfates (to give H2S and SO3) and dithionites (to give SO2) and heat. Reaction with solutions of carbonates and bicarbonates generate a harmless gas (carbon dioxide) but still heat. Can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. May initiate polymerization reactions. May serve as a catalyst.
Air and Water ReactionsDust explosion is possible. (USCG, 1999). Insoluble in water.

Anwendungen & Verwendung

Beschreibung

Undecanoic acid is a saturated fatty acid containing eleven carbons (C11:0). It is cytotoxic to certain filamentous fungi and is used to study fungal mechanisms of resistance. Undecanoic acid is also used to acylate larger molecules.

Occurrence

Occurs naturally in butter and in the oil of Artemisisa frigida Willd.; also reported found in the oils of Chamaecyparis pisifera Engl., wild thyme, Thymus marschollianus and coconut. Also reported found in apple, banana, sour cherry, lemon and mandarin peel oil, grapefruit juice, guava, grapes, papaya, many cheeses, milk powder, chicken and beef fat, cooked mutton, cured pork, beer, cognac, rum, whiskies, white wine, tea, coconut milk, beans, licorice, mango, mushrooms, rice, sake, wort, loquat, scallop and maté.
