Vapour pressure:
0.39 other: N/m2
Conclusions:
The vapour pressure of 2,6-di-tert-butyl-4-methylphenol at 298 K obtained by the gas saturation method was 0.39 N/m2.
Executive summary:

The vapour pressure of the test substance was measured over the temperature range 300 to 334 K (27 to 61 ºC) using the gas saturation method. The vapour pressure of 2,6-di-tert-butyl-4-methylphenol at 298 K obtained by the gas saturation method was 0.39 N/m2.

Description of key information

Based on the experimental results from the study report (key study), the vapour pressure at 24.85 ºC is 0.39 N/m2 (0.39 Pa).

Based on the experimental results from the scientific article, the vapour pressure is 0.0047 mmg Hg (0.63 Pa).

Based on the estimated data using EPI-Suite, the vapour pressure is 0.00177 at 25 ºC (0.24 Pa).
