Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

The vapour pressure regression curve equation was: log PT= -4261 * 1/T + 9.39 (r = 0.993, n = 8).

Conclusions:
The isothermal TGA effusion method was applied for the determination of the vapour pressure of Copper diethylenetriamine sulfate.
The vapour pressure of the test item at 20°C (293K) and 25°C (298K) was:
20°C: 5.3 * 10^-8 mm Hg
25°C: 9.4 * 10^-8 mm Hg
