数据库记载的用途

  • Used in organic synthesis; [Hawley]
  • 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/
  • 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
  • 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/
  • Gas-phase dehydrogenation of n-alkanes over noble-metal catalysts yield the corresponding n-alkenes at low conversion rates (ca. 10%) with predominantly internal double bonds. The corresponding alkenes can be isolated in high purity by selective molecular-sieve processes. /Higher n-Alkanes/
