Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Applicant's summary and conclusion

Conclusions:
The vapour pressure of test item, Hexyl Nitrite, was investigated. The isothermal thermogravimetry effusion method was used.

The course and and result of experiment showed that the value of vapour pressure of test item, Hexyl Nitrite, is out of range applicability of Effusion method: isothermal thermogravimetry (10-10 to 1 Pa).
Executive summary:

The losses of weight at temperature range from 50°Cto 80 °C were very high.The lower measuring temperature range was set and measured. The weight losses at temperature range from 30 °C to 60 °C were high. The crucible was empty after third temperature step – all test item disappeared.

Test item seems to be a substance with very high vapour pressure which is not measurable by Effusion method: isothermal thermogravimetry with range of measureng 10-10to 1 Pa.
