Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Individual Results

 

Thermal Stability

The DSC-measurement in a closed glass crucible with the test item showed and endothermic effect in the temperature range 200 – 230 ‘C directly followed by an exothermic effect in the temperature range 230 – 340 ‘C and a second exothermic effect in the temperature range 350 – 435 ‘C with an overall energy of 330 J/g.

A graphical presentation of the DSC run No. 27734 is given on page 8 (figure 1) of the study.

 

Vapour Pressure Balance (Effusion Method)

The vapour pressure was measure in the temperature range of 35 ‘C to 150 ‘C. Above 138 ‘C a vapour pressure could be measured. The measure vapour pressure at the corresponding temperatures are listed in the following table:

  Temperature / 'C  Vapour pressure / hPa 
  138.0  0.000015 
  138.2  0.000015 
  143.5  0.000019 
  148.1  0.000039 
  150.2  0.000054 

The figure 2 on page 9 of the study gives the vapour pressure (logarithmic scale) as a function of the inverse temperature (1/T, T in Kelvin). Only for better readability the temperature is reported in a centigrade scale. The values for 20, 25, and 50 'C are calculated, using the Antoine constants A, B and C as shown there.
