Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The density of the substance was found to be 1.06 g/cm3.

Executive summary:

In the Handbook of Environmental Data on Organic Chemicals, the relative density of the substance is reported to be 1.06 g/cm3.

Description of key information

Triethylphosphat is reported to have a density of ca 1,066 g/cm3, assumed to be at ambient temperature. (handbooks) 

Key value for chemical safety assessment

Relative density at 20C:
1.066

Additional information

Two handbooks, considered as reliable sources, report similar density values for the substance, and are therefore presented in a Weight-of-Evidence approach:


The Merck Index (2001) reports a density of 1.0725 g/cm3, and Verschueren (1996) reports 1.06 g/cm3. Temperature is not specified, but assumed to be ambient.


The average (rounded) value is retained as key data. Assuming a density of 0,9998 g/cm3 for water at 4°C, the relative density D20/4 for the test substance is 1,066.
