- 暴露限值:
- Flammable liquid; flash point (closed cup) 36°C (97°F) (NFPA 1986), 39°C (102°F) (Merck 1996), 35.5°C (96°F) (Meyer 1989); vapor pressure 8 torr at 20°C (68°F); vapor density 4.1 (air=1); the vapor is heavier than air and may travel a considerable distance to a nearby ignition source and flash back; autoignition temperature 425°C (797°F); fire- extinguishing agent: dry chemical, foam, or CO2; use a water spray to keep fire- exposed containers cool and to disperse the vapors。Cumene forms explosive mixtures in the air within the range 0.9–6.5% by volume in air. Cumene may form peroxide on prolonged exposure to air. It should be tested for peroxides before it is subjected to distillation or evaporation。.

- 稳定性:
- Stable, but may form peroxides in storage if in contact with the air. Test for the presence of peroxides before heating or distilling. Combustible. Incompatible with strong oxidizing agents.
