A plot Log₁₀(vapour pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 5 gives the following statistical data using an unweighted least squares treatment.

Slope -8114.666

Standard deviation in slope 291.807

Intercept 18.221

Standard deviation in intercept 0.698

The results obtained indicate the following vapour pressure relationship.

Log₁₀(Vp (Pa)) = -8114.666/temp(K) + 18.221

The above yields a vapour pressure (Pa) at 298.15 K with a common logarithm of -8.996.

Summary of Results

Run	Log10 [Vp(25°C)]
1	-7.233
2	-6.826
3	-8.015
4	-6.353
5	-8.996
Mean = -7.485 Vapour Pressure = 3.3 x 10^-8Pa

The test material did not change in appearance under the conditions used in the determination.

Conclusions:

The vapour pressure of APAN has been determined to be 3.3e-8 Pa at 25 °C.

Executive summary:

The test procedure was based on Method A4 specified in Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).

APAN has been determined to have a vapour pressure of 3.3 x 10^-8Pa at 25 °C, using a vapour pressure balance.
