Henry's Law Constant13.0, 15.3, and 23.9 at 28.0, 35.0, and 46.1 °C, respectively (headspace method, Hansen et al., 1993)
Dielectric constant2.4（20℃）
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.
