Comment

During the analysis, the sample was degassed at around -10°C. From available information, the sample is a reaction product and therefore has multiple components.

Since the sample was tested in the as received condition the chemistry of the sample (i.e. individual components) must be considered when interpreting the vapour pressure result.

About 40 mL of sample was used in Run 1 and 22 ml of sample during Run 2.

Conclusions:
The following vapour pressure result was obtained: 2176 Pa @ 20°C (mean of 2 runs)
