Uses and applications

What the substance is used for, by industry and function

Organic synthesis.

They are used mainly in applications for which isoalkanes are not acceptable for biological reasons, e.g., the production of detergents or proteins./Higher n-Alkanes/.

Solid n-alkanes (paraffin waxes) are used in a variety of applications, e.g., ... oxidation, and chlorination reactions. (Higher n-Alkanes).

Roles

  • eukaryotic metabolite
  • metabolite
  • plant metabolite
  • volatile oil component

How it is made

The liquefaction of coal provides the greatest variety of saturated hydrocarbons. The Fischer-Tropsch synthesis produces alkanes from syngas (CO + H2) in the range C1 to C30 or higher depending on the process variant: depending on the catalyst employed, the synthesis yields predominantly liquid hydrocarbons in the gasoline range, along with gases from C1 to C4 when iron-based catalysts are used, while cobalt-based catalysts produce longer chain hydrocarbons in the diesel and wax range that often undergo, depending of the desired product slate, further processing, especially for gasoline genera

tion. While iron-based Fischer-Tropsch catalysts generate complex mixtures that also include branched and olefinic hydrocarbons, cobalt-based catalysts produce streams that are rich in n-alkanes and are therefore suitable raw materials for detergents and for wax products. (Saturated Hydrocarbons)

Suitable sources for n-alkanes with more than six carbon atoms are the appropriate petroleum distillate fractions, from which the n-paraffins can be isolated in high isomeric purity (= 95% linearity) by selective separation techniques, especially fractional distillation. (Higher n-Alkanes)
