Description of key information

For the pure solid guanidinium chloride the vapour pressure is expected to be much lower than 0.000005 Pa.

Key value for chemical safety assessment

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

Additional information

The vapour pressure of free guanidine is 293 Pa (HSDB). With Dalton's law the vapour pressure of free guanidine of an 1 molar solution in water calculates to 0.0000053Pa.

For the pure solid guanidinium chloride the intermolecular binding forces are much higher than for the solution in water, corresponding to the melting point of 188 °C. Therefore the vapour pressure is expected to be much lower than 0.000005 Pa
