results of the isothermal TGA analysis for the test item are
At the start of the measurements weight loss, due to evaporation
of volatile components (i.e. water), was observed.
Weight loss was determined in the range of 100°C – 130°C. No
reliable vapour pressure could be determined, since non-linear weight
loss was observed. The correlation of variation R was <0.99 within this
temperature range for the first measurement and the two measurements
combined. As the only alternative, the weight losses of the test item
were compared with the weight losses of hexachlorobenzene. Since
the weight loss of the test item was lower than the weight loss of
the reference compound, the vapour pressure of the test item is
considered to be lower than that of hexachlorobenzene. The
corresponding values are given inTable 3.

Table 3: Vapour pressure of the Test Item
The isothermal TGA effusion method was applied for the determination of
the vapour pressure of Acetic acid, oxo-, sodium salt, reaction products
with ethanolamine and phenol, sodium hydroxide and ferric chloride.
The vapour pressure of the test item at 20°C (293K) and 25°C (298K) was
<0.0015 Pa and <0.0041 Pa, respectively.
