Description of key information

The vapour pressure of tetraethylammonium hydroxide at 25°C was calculated to be 8.14E-07 Pa using Episuite mpbpwin v1.43 (modified Grain method).
It is assumed that the vapour pressure of the registered substance, an aqueous solution, is at approximate the same as the vapour pressure of water (2.3E03 Pa at 20°C; CRC Handbook of Chemistry and Physics, 80th ed., Lide, D, CRC Press, 1999 -2000).

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
