Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Any other information on results incl. tables

As the test material decomposed, no value for the boiling point could be determined. It is also not possible to calculate a definitive boiling point temperature from the data obtained in the vapour pressure study for this test material since only the maximum vapour pressure was determined. This is due to the test material being solid and non-volatile, thus the vapour pressure readings were too low and variable. Based on the limit value obtained in the vapour pressure study and on the chemical structure of the substance a boiling point was estimated to be > 633 K (360°C) at 101.325 KPa

Applicant's summary and conclusion

Executive summary:

Arakawa KE-604 has been determined to decompose from 453 ± 0.5 K prior to any boiling, at an atmospheric pressure of 101.325 KPa.

As the test material decomposed, no value for the boiling point could be determined. Using the data obtainded from the vapour pressure study and the chemical structure of the substance, the boiling temperature is estimated to be >633 K at 101.325 KPa.
