Reference
No change in appearance of the test substance, Veova Neo 10, Intertek Reference 10467578, during the analysis was noted, indicating that no test substance degradation had occurred.
The test substance boiled at 1026mBar (atmospheric pressure) giving a boiling point of 185.9°C.
The pressure was reduced gradually until a boiling point was observed at 25mBar. The boiling point at 25mBar = 84.9°C.
Multiple data-points were recorded between 1026 and 25mBar and 185.9 and 84.9°C respectively (Figure 1), to generate a vapour pressure curve (Figure 2) to allow vapour pressure determination at 25°C.
