Boiling point at 101 325 Pa:
207 °C

Additional information

Due to the thermal instability (starts to polymerise at 141.5 °C at ca.1013 hPa) of the substance Methacryloxyethyl isocyanate  (CAS 30674-80-7) the boiling point of the substance was determined by the distillation method on reduced pressure (3.47 hPa). To support the experimental values the calculations using SPARC (v.4.6) were done on the same condition (3.47 Pa) as well as on normal pressure (1013 hPa). The calculated values are comparable with experimental results. For this reason would be assumed, that the test substance has the same vapor pressure (ca. 200 °C) at 1013 hPa.
