Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The boiling point of octadecyl isocyanate is 172°C at 6.67 hPa.
Key value for chemical safety assessment
Additional information
There is no reliable data available for the test substance itself. But as results are present for one main constituents of the reaction mass (65%), this data is taken into account for further assessment as read-across approach. It is assumed that due to the similarity of the chemical structures of both main constituents the ecotoxicological hazards of the reaction mass can be described with data of one or both main components as a realistic approach.
The reaction mass of hexadecyl isocyanate and octadecyl isocyanate, as defined in section 1, consists of 35 % of hexadecyl isocyanate and 65 % of octadecyl isocyanate. Therefore, octadecyl isocyanate was regarded in this read-across approach.
The reported pressure is 6.67 hPa. No reliable boiling point at 1013 hPa is available.
The Material Safety Data Sheet reported a boiling point of ca. 208°C at 20 hPa for the reaction mass.
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.
