About Heptane

Heptane (C₇H₁₆) is a straight-chain alkane hydrocarbon derived from petroleum refining. Its narrow boiling range and low aromatic content make it a preferred solvent where residue and odor need to stay low — including as the denaturant in CDA-12A ethanol blends.

Superior Chemical Co. supplies both ultra-low-aromatic heptane, for applications sensitive to aromatic content, and high-purity heptane for general industrial solvent use.

Common industrial uses

  • Denaturant for CDA-series ethanol blends
  • Rubber cement and adhesive formulation
  • Octane reference fuel and calibration standard
  • Extraction and degreasing solvent
  • Printing and coatings solvent

Frequently asked
Why is heptane used to denature ethanol?
Heptane is added to ethanol in small, controlled ratios (as in CDA-12A) to render the product unfit for beverage consumption, which exempts it from beverage alcohol taxation while keeping the blend suitable for extraction and industrial use.
What does 'ultra low aromatics' mean?
It refers to a heptane grade refined to minimize aromatic hydrocarbon content, which matters for applications sensitive to trace aromatics — including certain extraction and analytical processes.
What container sizes are available?
Heptane ships in 55-gallon drums, 275-gallon totes, 7,700-gallon tankers, or 28,500-gallon railcars.
