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
