CAS number: -
The boiling point of octadecyl isocyanate is 172°C at 6.67 hPa.
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
The Material Safety Data Sheet reported a boiling point of ca. 208°C at
20 hPa for the reaction mass.
