Description of key information

Vapour pressure: 0.31 Pa at 25 deg C

Key value for chemical safety assessment

Vapour pressure:
0.31 Pa
at the temperature of:
298.15 K

Additional information

All the vapour pressure estimations of hexahydro-4-methylphthalic anhydride, calculated using several methods, lead to results having the same order of magnitude.

Therefore it appears reasonable to calculate the mean of them, to obtain a summary value suitable for the assessments of the above substance.

VP= (0.19 +0.23+ 0.49 +0.33)/4= 0.31 Pa
