Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Conclusions:
- High volatility (based on volatility bands criteria for occupational exposure (Chesar / ECETOC TRA), > 10 kPa).
- Executive summary:
The CRC Handbook provides six Vapour Pressure/Temperature pairs for the substance, between 1 Pa and 100 kPa.
From these data, the interpolated VP at 20°C is expected in the range ca 71.5 - 95.7 kPa.

- Executive summary:
The HSDB database provides, as secondary source, physico-chemical data on the substance.
The vapour pressure, cited from Perry's handbook, is 84.6 kPa at 25°C.

The linear regression was calculated from all available points, and found quite good despite the wide range:
log VP (Pa) = -1588.7 / T (K) + 10.401; r2 = 0.9938
The extrapolated VP at 20°C was calculated as 95.7 kPa.
A similar calculation was performed with only the two points closer to ambient temperature:
log VP (Pa) = -1345.8 / T (K) + 9.445; r2 = 1
The extrapolated VP at 20°C was calculated as 71.5 kPa.

Description of key information
(from handbooks)
High volatility.
Key value for chemical safety assessment
- Vapour pressure:
- 84.6 kPa
- at the temperature of:
- 25 °C
Additional information
Three literature sources provide a wide range of values, between -119 to + 50°C (gas). In the common temperature range, i.e. between ca 20 and 30°C, which is the boiling point, these values are consistent, around 70 - 101 kPa.
From the two references considered as reliable (HSDB and CRC), the result from HSDB is prefered and retained as key data, as the correponding temperature is below the boiling point, therefore refering to the liquid state. While from CRC, the value at 20 or 25°C has to be interpolated from the series.
