Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
relative density
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2011-05-23
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
comparable to guideline study with acceptable restrictions
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)
Qualifier:
equivalent or similar to guideline
Guideline:
EU Method A.3 (Relative Density)
Principles of method if other than guideline:
The density of the liquid is measured by a pycnometer made of glass with a close-fitting ground glass stopper with a capillary tube through it, so that air bubbles may escape from the apparatus. The device enables a liquid´s density to be measured accurately by reference to an appropriate working fluid using an analytical balance. The flask is weighed empty and full of a liquid whose specific gravity is desired, the specific gravity of the liquid can be then calculated.

Conclusions:
Using the pycnometer method, the density of tert-Butylperoxyneodecanoat (TBPND) was determined to be 0.898 g/cm³ at 20 ± 0.2 °C.
Executive summary:

The density of the test substance tert-Butylperoxyneodecanoat (TBPND) (~98 % purity) was measured by a 25 mL pycnometer at temperature of 20 +/- 0.2 °C. The calculated result obtained indicated of a density of 0.898 g/cm³ for TBPND.
