Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of tetramethylene diamine is evaluated inhouse based on literature data in combination with measurepoint within DSM.
The value by 25°C is 436 Pa.
This is line with the Episuite calculation (Mackay Method) 454 Pa.
Chemical with a relatively low vapour pressure or high solubility in water are less likely to vaporise and become airborne than chemicals with a high vapour pressure or less affinity for solution in water. The vapour pressure of tetramethylene diamine is lower than the vapour pressure of water (3200 Pa).
