High purity substances

DHC has the know-how and the technology necessary for extremely fine distillation required to manufacture extremely pure products.

Examples of primary applications/processes for pure products with a purity of > 95% respectively > 99% mass fraction:

n-Hexane

  • Solvent and reaction agent for polymerisation
  • Production of plastics and synthetic rubber
  • Elution agent and solvent in thin-layer chromatography and spectroscopy

n-Heptane

  • Solvent in the production of catalysts
  • Elution agent for molecular sieve plants
  • Reaction agent for polymerisation
  • Test substance for Otto-engine fuels
  • Analytical purposes
