Description of key information

The vapour pressure of TGIC has been determined experimentally and by calculation.  In the experimental studythe valuefound was 0.0072 Pa at 20°C, and via calculation a lower value of 0.00091Pa (at 60°C) has been determined.

Key value for chemical safety assessment

Vapour pressure:
0.007 Pa
at the temperature of:
293.15 K

Additional information

The measured vapour pressure of 0.0072 Pa (20°C) is probably more reliable than the calculated one which is almost 10 -times lower at a higher temperature (60°C). A vapour pressure of 0.0072 Pa is however quite high when comparing it to another triazine - Atrazine which has a VP=0.00003853 Pa (at 20°C), or Simazine with a VP=0.000002946 Pa (at 20°C), or Cyanuric acid with a VP=0.0000040 Pa (at 20°C). This means that the real vapour pressure is probably at least one order of magnitude lower than the existing value, namely in the order of 0.0001 - 0.0007 Pa (at 20 °C)
