Uses and applications

What the substance is used for, by industry and function

Solvent, organic synthesis, distillation chaser, jet fuel research.

Manufacturing paraffin products ... Lubricant oil additive.

Dodecane is a component of gasoline and is used as solvent, in organic synthesis, in jet fuel research, as a distillation chaser, and in the rubber and paper processing industries.

We have recommended surrogate blends for Fischer-Tropsch (F-T) blends that consist of mixtures of n-dodecane, n-decane, and iso-octane. In addition, we have described a systematic approach to generating a specific blend to match a specific fuel. Compositions for specific surrogates of two different F-T fuels have been proposed that provide a best match to cetane number, H/C ratio, lower heating value, T50 boiling point, and chemical-analysis data.

How it is made

1-Hexene is hydroborated with sodium borohydride and boron trifluoride in diglyme. Aqueous potassium hydroxide is then added followed by aqueous silver nitrate. The major product is n-dodecane (66%).

Dodecane is isolated from the kerosene and gas oil fractions of crude oil by selective adsorption and subsequent desorption to yield mixtures of paraffins that can be separated by fractional distillation.
