Applicant's summary and conclusion
- Conclusions:
- The vapour pressure was examined at 3 different temperatures. The vapour pressure of the known constituents has been determined. The vapour pressure ranges between 2.64 x 10-4 Pa (constituent with highest molecular weight) and 5.93 x 10-4 Pa (constituent with lowest molecular weight) at 20°C.
- Executive summary:
The vapour pressure of the test item BTG Pyrolytic Lignin was determined at three different temperatures (75, 90 and 105 °C) according to OECD 104 resp. EU A.4 using the effusion method (Knudsen cell).
The test item is a complex reaction product consisting of several chemical constituents, and therefore the vapour pressure was calculated based on the molecular mass of a number of known constituents. The vapour pressure ranges between 2.64 x 10-4 Pa (constituent with highest molecular weight) and 5.93 x 10-4 Pa (constituent with lowest molecular weight) at 20°C.
