Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Diss Factsheets

Administrative data

boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The result was obtained from a collection of reliable data which has been subject to peer-review and in which the original data sources are traceable.

Data source

Reference Type:
review article or handbook

Materials and methods

Principles of method if other than guideline:
Experimental measurement (data is taken from a reliable handbook, information about the methodology is not available).
GLP compliance:
Type of method:
other: From a handbook

Test material

Constituent 1
Reference substance name:
propylene oxide
propylene oxide
Constituent 2
Reference substance name:
EC Number:
EC Name:
Cas Number:
Details on test material:
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.

Results and discussion

Boiling point
Boiling pt.:
34.1 °C
Atm. press.:
101.325 kPa

Any other information on results incl. tables

A value of 34.1°C (Jefferson Chemicals, 1960) was quoted using a modified ASTM method (D-1078). Other values quoted without supporting data were 34°C at 101.325 kPa (BASF AG Material Safety Data Sheet, 1995), 34.3°C and 34°C (BASF AG Technische Information, 1993 and Dow Material Safety Data Sheet, 1987, respectively) and 34.3°C and 34°C at 101.3 kPa (BASF, 1981a and 1967, respectively). A value of 34.196°C at 101.325 kPa has been calculated from vapour pressure data, using the Antoine equation (ESDU, 1988). A measured boiling point of 33.9°C at 101.325 kPa (the American Chemical Society Monograph Series: Glycols, 1952) has also been quoted.

Applicant's summary and conclusion

A boiling point value of 34.1°C is reported at 1013 hPa in a risk assessment summary report with 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.
