Description of key information

Read across. The vapour pressure of N-C12,14 alkyl-1,3-diaminopropane was determined to be 1.5 mPa at 20°C.

Key value for chemical safety assessment

Vapour pressure:
0.002 Pa
at the temperature of:
20 °C

Additional information

Read across. As a worst case, the vapour pressure is read across from a substance with lower carbon chain distribution from the diamine category. Since the vapour pressure increase with decreasing hydrophobe in a specific homologue, it is a worst case to read across from a substance with lower carbon chain distribution. Furthermore, in terms of the hydrophilic group, the vapour pressure is higher over the diamine (not quaternized) that over its quaternized ammonium chloride salt.
