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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion
Boiling point
- Decomposition:
- yes
- Remarks:
- The boling point of "D-VAL-DANE" could not be determitated because the test substance decomposes
- Remarks on result:
- other: The boling point of "D-VAL-DANE" could not be determitated because the test substance decomposes
Any other information on results incl. tables
The boiling point of "D--DANE" could not be determined because the test substance decomposes.
The test substance melts at over 200°C. After the insertion of a boiling capillary the test substance seems to boil. When the temperature is lowered again, the “boiling” stops only when the substance solidifies. The amount of test substance was markedly reduce without any condensate at the top of the boiling tube.
So it is evident that this “boiling” is not caused by the vapor of the test substance but rather by a gaseous decomposition product. A real boiling (changing from the liquid to the gaseous phase) could not be achieved.
The different behaviour of the test substance in this test (melts at over 200°C) and in the determination of the meling point (does not melt) may be due to the different rate of heating.
Applicant's summary and conclusion
- Conclusions:
- Not appropriate as the test substance decomposes before melting
