Administrative data

Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2002
Reliability:
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
Reference Type:
review article or handbook
Title:
Unnamed
Year:
2002

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:
no
Type of method:
other: From a handbook

Test material

Reference
Name:
Unnamed
Type:
Constituent
Type:
Constituent
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 R(+) 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

Conclusions:
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.
