Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
It is not possible to conduct an actual point boiling study for triisotridecyl phosphite because the substance will decompose prior to reaching the very high boiling point. (see supporting study)
The MPBPVP V1.43 model, part of EPISuite 4.1, was used to develop an estimated boiling point, which was predicted to be 520.01 deg C (adapted Stein and Brown Method).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 520 °C
Additional information
It is not possible to conduct an actual point boiling study for triisotridecyl phosphite because the substance will decompose prior to reaching the very high boiling point.
The MPBPVP V1.43 model, part of EPISuite 4.1, was used to develop an estimated boiling point, which was predicted to be 520.01 deg C (adapted Stein and Brown Method).
Various possible structures were consideredfor iso branched C39H81O3P1, with 520 deg C being the lowest calculated value as such this will be used in the CSR
The model has been validated by the camparison of the calculated value of the iso tridecanol with the measured value of approximately 260 deg C
The high boiling point of the Trisisotridecyl phosphite is not unexpected considering that it is more than 3 times the molecular weight of the starting alcohol which itself has a boiling point of ca 260 deg C
The high boiling point of Tridisotridecyl Phosphite would also be anticipated when considered against its manufacture high temperature and low vacuum conditions -at which it does not boil
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
