Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Endpoint:
boiling point
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because chemical change occurred during the melting point study
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
According to the results obtained in the OECD 104 test (vapour pressure determination), the substance polymerises at a temperature of approx. 130 °C and at a pressure of approx. 10hPa; at lower temperatures no boiling of the test item has been observed.

Individual Results

Thermal Stability (DSC)

A DSC-measurement in closed glass crucible showed a small exothermic effect in the temperature range of 170 - 220 °C and a broad exothermic effect in the temperature range of 245 - 445 °C with an overall energy of 534 J/g.

Vapour Pressure (Dynamic Method)

For filling the test apparatus, the test item was liquefied by heated up to approximately 60 °C. No vapour pressure could be measured because the test item polymerises at a temperature of approximately 130 °C and at a pressure of approximately 10 hPa. At lower temperatures no boiling of the test item could be observed.

Conclusions:
No vapour pressure could be measured because the test item polymerises at a temperature of approximately 130 °C and at a pressure of approximately 10 hPa.
Executive summary:

The vapour pressure of the test substance has been determined in a GLP test according to EU Method A.4 and OECD Guideline 104. In addition, a screening test for thermal stability and stability in air has been conducted according to OECD Guideline 113 (DSC). No vapour pressure could be measured as the test item polymerises at a temperature of ~ 130 °C (and at 10 hPa). At lower temperatures no boiling of the test item could be observed.
