Hazard Information

General Description
Clear colorless liquid.
Reactivity Profile
Saturated aliphatic hydrocarbons, such as N-DODECANE(112-40-3), 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. When heated sufficiently or when ignited in the presence of air, oxygen or strong oxidizing agents, they burn exothermically to produce carbon dioxide and water.
Air & Water Reactions
Flammable. Insoluble in water.
Fire Hazard
This chemical is combustible.

Questions And Answer

Description
Dodecane is a liquid alkane hydrocarbon that is found in black walnut that has 355 isomers. It is an oily liquid of the paraffin series. Dodecane is a colorless liquid that has a boiling point of 421.3° F at 760 mm Hg and a melting point of 14.7° F. It is very soluble in ethyl ether, ethyl alcohol, carbon tetrachloride, and chloroform. Dodecane is stable under recommended storage conditions. However, under elevated temperatures, it decomposes to emit irritating fumes and smoke.
Preparation Method
1-Hexene is hydroborated with baron trifluoride and sodium borohydride in diglyme. Aqueous potassium hydroxide is then added followed by aqueous nitrate. Dodecane is produced as the product.
Applications
Dodecane may be utilized as an inorganic diluent to form an organic phase together with tri-n-octylamine as an extractant and decanol as an active diluent. Notably, this system can also be employed in the extraction of lactic acid from aqueous solutions.
Food Additives
Dodecane can be used as a flavoring agent in food processing
Industrial Uses
Dodecane has been used in the aviation industry as an alternate for kerosene-based fuels such as Jet-A. It has also been used as a lubricant and additive to lubricants.
Consumer Uses
Dodecane is used as an adhesive and sealants.
