Additional information

A vapour pressure of 2770 Pa at 20 °C and 3498 Pa at 25 °C was measured by using a static method.

These values were calculated from the regression equation of 18 individual measurements.

SCP liquor is an aqueous solution. The values recorded at increasing and decreasing temperatures showed differences at lower temperatures. Possibly, the test item decomposed partly during the heating phase.
