Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 3,6,9-Triethyl-3,6,9-trimethyl-1,4,7-triperoxonane in 55% Petroleum distillates is 4.1 Pa at 25°C.
- Executive summary:
The vapour pressure of the product is measured. So it is not determined if the vapour pressure is caused by 3,6,9-Triethyl-3,6,9-trimethyl-1,4,7-triperoxonane or Petroleum distillates or both.
The vapour pressure of 3,6,9-Triethyl-3,6,9-trimethyl-1,4,7-triperoxonane in 55% Petroleum distillates is 4.1 Pa at 25°C.
Reference
A plot of Log10(vapour pressure (Pa)) versus reciprocal temperature (1/T(K)) gives the following statistical data using an unweighted least squares treatment. See attachment.
Slope -6710.907
Standard deviation in slope 1659.746
Intercept 23.117
Standard deviation in intercept 5.565
The results obtained indicate the following vapour pressure relationship.
Log10(Vp(Pa)) =-6710.907 / temp(K)+ 23.117.
The above yields a vapour pressure (Pa) at 298.15 K with a common logarithm of 0.608 which is equivalent to a vapour pressure of 4.1 Pa.
Description of key information

Additional information
The vapour pressure of the product is measured. So it is not determined if the vapour pressure is caused by 3,6,9-Triethyl-3,6,9-trimethyl-1,4,7-triperoxonane or Petroleum distillates or both.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
