Physical description & handling notes

• 1-octene appears as a colorless liquid. Flash point 70 °F. Insoluble in water and less dense (at about 6 lb / gal) than water. Hence floats on water. Vapors are heavier than air and may settle in depressions. Reported to biodegrade very slowly. Used in organic synthesis, surfactants, and plasticizers.
• Liquid
• Colorless liquid; [ICSC]
• Colorless liquid; [HSDB]
• COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR.
• Colourless liquid, Petroleum-like aroma
