The vapour pressure regression curve equation was:

log PT= -4976 * 1/T + 11.58 (r = 0.992, n = 8).

Conclusions:
The isothermal TGA effusion method was applied for the determination of the vapour pressure of Reaction product of copper sulfate and triethylenetetramine.
The vapour pressure of the test item at 20°C (293K) and 25°C (298K) was:
20°C: 3.0 * 10^-8 mm Hg
25°C: 5.9 * 10^-8 mm Hg
