- Executive summary:
o-Chlorobenzaldehyde showed vapour pressures of 4.6 Pa (20°C), 8.3 Pa (25°C) and 95.2 Pa (50°C) in a study conducted according to EU testing method A.2 and OECD testing guideline 103.
Reference
The values for 20, 25 and 50 °C were calculated using Antoine constants:
A: 6.13628
B: -1046.87
C: 1200.02
with the equation log (p/hPa) = A + B/(C+T[°C]).
