Description of key information
The vapor pressure of Isodecyl methacrylate is 0.0156 hPa at 25°C (Calculation using EpiWin version 4.00).
Key value for chemical safety assessment
- Vapour pressure:
- 0.016 hPa
- at the temperature of:
- 25 °C
Additional information
Conclusion
The vapor pressure of Isodecyl methacrylate is 0.0156 hPa at 25°C (Calculation using EpiWin version 4.00). This value for the vapor pressure of Isodecylmethacrylate lies in the same order of magnitude as the measured and extrapolated value for the structural analog substance n- Decyl methacrylate (0.0127 hPa) at 20°C. The vapour pressure is following the general trend of decreasing vapor pressure with increasing ester size: 2 -Ethylhexyl methacrylate (0.065 hPa); Dodecyl methacrylate (0.06 Pa).
