Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Conclusions:
- The vapour pressure of DL-ISOLEUCINE, N-(1-OXOHEXADECYL) extrapolated at
20 °C is P = 2.0 x 10-6 Pa.
The vapour pressure of DL-ISOLEUCINE, N-(1-OXOHEXADECYL) extrapolated at
50 °C is P = 2.9 x 10-4 Pa.
For results obtained at lower temperatures than the melting point of the test item, the slope of the equation is higher than the slope of the equationfor results obtained at higher temperatures than the melting point of the test item. As a consequence, the above calculated values are overestimated.
To conclude, we can consider that the real vapour pressure of
DL-ISOLEUCINE, N-(1-OXOHEXADECYL) is largely lower than the values obtained above by extrapolation. - Executive summary:
In compliance with
Commission Regulation (EC) No. 761/2009
EC A4 method (2009) and OECD Guideline No. 104 (2006)
The vapour pressure of DL-ISOLEUCINE, N-(1-OXOHEXADECYL) extrapolated at
