Vapour pressure:
ca. 71 Pa
Remarks on result:
other: The vapour pressure of the test item is given as the mean value of two measurements.

The sample degassed to constant vacuum pressure while stirring for 17 hours. The results of the two measurements are given below.

    Test 1     Test 2
 Temperature (°C)  Vapour pressure (Pa)   Temperature (°C)   Vapour pressure (Pa)
 20*  72  20*  70
 20.2  73.28  20.3  72.96
 31.9  91  30.0  87
 39.9  110  45.0  120
 48.9  140  65.0  180
 66.9  180 75.1   220

*The vapour pressure at 20°C was determined by extrapolation.

Conclusions:
The vapour pressure of 3,6-dioxaoctamethylenediamine was determined to be 71 Pa at 20.0°C.
