n-Hendecane Usage And Synthesis

Chemical Properties	colourless liquid.
Uses	Petroleum research, organic synthesis, distillation chaser.
Uses	Undecane is used in preparation method of small-size hollow Silicon Dioxide.
Uses	Undecane is mainly used as a model n-alkane in studies relating to viscosities, excess molar enthalpies and vapor-liquid equilibrium of binary alkane mixtures.
Definition	ChEBI: Undecane is a straight-chain alkane with 11 carbon atoms.
Production Methods	Undecane is obtained from the refining of petroleum. Paraffins are isolated by selective adsorption followed by fractional distillation to produce the desired mix of nparaffins (63).
Synthesis Reference(s)	Journal of the American Chemical Society, 95, p. 6131, 1973 DOI: 10.1021/ja00799a058 The Journal of Organic Chemistry, 50, p. 3082, 1985
General Description	A colorless liquid. Insoluble in water and less dense than water. Flash point 130°F. Used to make other chemicals.
Air & Water Reactions	Flammable. Insoluble in water.
Reactivity Profile	Saturated aliphatic hydrocarbons, such as n-Hendecane, may be incompatible with strong oxidizing agents like nitric acid. Charring of the hydrocarbon may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, aliphatic saturated hydrocarbons are mostly unreactive. They are not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents.
Health Hazard	Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Safety Profile	Moderately toxic by intravenous route. Flammable liquid when exposed to heat, sparks, flame, or oxidizers.To fight fire, use foam, mist, dry chemical. Emitted from modern buildmg materials (CENEAR 69,22,91). When heated to decomposition it emits acrid smoke and irritating fumes. See also ALKANES.
Carcinogenicity	Undecane (25 mg) and benzo[a] pyrene (B[a]P) (5 mg) were applied to the skin of female ICR/ Ha Swiss mice for 3/week for 440 days, inducing papillomas in 41 of 50 animals. B[a]P alone induced tumors in 12 of 50 animals in the same time, while undecane alone did not produce tumors.
