Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Test material

Constituent 1
Reference substance name:
propylene oxide
IUPAC Name:
propylene oxide
Constituent 2
Reference substance name:
Methyloxirane
EC Number:
200-879-2
EC Name:
Methyloxirane
Cas Number:
75-56-9
IUPAC Name:
2-methyloxirane
Details on test material:
>99.8 mole % pure, containing 0.12 mole % water;
Test material was racemate from both R(+) and S(-) propylene oxide. This endpoint is not measured / determined with enantio-selective sensors.
Therefore the S(-) value is identical to the racemate endpoint.

Any other information on results incl. tables

The density of propylene oxide, (>99.8 mole % pure, containing 0.12 mole % water), was determined by pycnometer to be 831 kg.m-3 at 20°C (BASF, 1977b). This is equivalent to a relative density (D4 20) of 0.831 and is in close agreement with the value of 0.8305 (Jefferson Chemicals, 1960) also determined by pycnometer.

Applicant's summary and conclusion

Conclusions:
A density value of 0.831 g/cm³ is reported at 20°C in a collection of reliable data which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable.
