Physical description & handling notes

  • N-heptene appears as a colorless liquid. Insoluble in water and much less dense than water. Vapors heavier than air. Used to make other chemicals.
  • Liquid
  • Colorless liquid; [HSDB]
  • Colorless liquid; [CAMEO] Distinct odor; [Matheson Tri-Gas MSDS]
  • Colorless liquid

GHS Hazard Classification

Reported hazard statementsH225 (100%), H304 (100%), H400 (100%), H410 (100%), H315 (68.2%), H319 (68.2%), H335 (13.6%), H320

H225 (100%): Highly Flammable liquid and vapor [Danger Flammable liquids]

H304 (100%): May be fatal if swallowed and enters airways [Danger Aspiration hazard]

Documented Uses

  • Used in the organic synthesis of flavors, perfumes, pharmaceuticals, dyes, oils, and resins; [HSDB]
  • Used to make other chemicals; [CAMEO] Manufactured and used strictly as component of C6-C8 distillation cut; [IUCLID] Typical uses for C6-C8 olefins include intermediates for low-molecular weight fatty acids and mercaptans; Uses for C6-C10 olefins include intermediates for plasticizer alcohols and surfactants; [OECD SIDS: Higher Olefins - 2004]
  • The One-Step Ziegler Process involves the oligomerization of ethylene in the presence of trialkylaluminum at 180-220 °C and 140 atm.
  • The Two-Step Ziegler Process involves the oligomerization of ethylene in the presence of aluminum alkyls at 175-200 °C and 136-204 atm. Chain growth continues with the reaction of light olefins with the aluminum alkyls continuously fed in stoichiometric amounts.
  • High purity ethylene contacts a nickel catalyst in a butanediol reaction medium. The alpha-olefins produced, separate from the solvent because they are insoluble in the polar medium.
  • Alpha-olefins of C4, C6-C15 and >C20 are by-products of oligomerization reactions.
