Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- 639.74 °C
Additional information
The boiling temperature of the substance " Reaction mass of dodecane-1-thiol and tridodecyl trithiophosphite" was investigated. The Differential Scanning Calorimetry method was used. The procedure used was similar to OECD TG 103. After melting at 19.8 °C, the decomposition of test item starts at 300 °C with a peak at 337.98 °C correlated to ΔH= 58.16 J/g. Before decomposition the evaporation of one impurity at 162.88 °C (probably diethyl phosphonate) was registered. The boiling temperature of the test substance could not be determined because of its thermal decomposition.
An estimated value of boiling point of 639.74 °C has been calculated by EPI Suite v.4.11 using the SMILES notation CCCCCCCCCCCCSP(SCCCCCCCCCCCC)SCCCCCCCCCCCC for its most abundant component Tridodecyl trithiophosphite.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
