Any other information on results incl. tables
Based on the low estimated vapour pressure of diisotridecyl phenyl phosphite, the flash point of the pure substance is expected to be high. Phosphonates of this type are known to hydrolyse at high temperatures in contact with atmospheric moisture. In the case of diisotridecyl phenyl phosphite this hydrolysis liberates isotridecanol and phenol.
The flash point of isotridecanol is 128ºC (as stated in the REACH dossier 27458-92-0)
The flash point of phenol is 79°C (as stated in the REACH registration dossier 108-95-2)
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The flash point of diisotridecyl phenyl phosphite can be stated to be greater than or equal to 79ºC, which is the flash point of phenol (a decomposition product).
- Executive summary:
The flash point of diisotridecyl phenyl phosphite can be stated to be greater than or equal to 79ºC, which is the flash point of phenol (a decomposition product).
