Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

The measured values (P) are plotted against the reciprocal of the temperature (1/T) for each temperature condition, after which the regression curve is calculated.

Regression curve:

log P =－3040.84×1/T＋12.6473

P: measured value (P)

T: temperature (K)

Based on the regression curve, the vapor pressure of the test material at 25 °C (extrapolated value) is 2.81 × 102Pa.
