Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
melting point/freezing 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 handbook 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 review report, information about the methodology is not available)

GLP compliance:
no
Type of method:
other: From a report

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:
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

Melting / freezing point
Melting / freezing pt.:
ca. -112.6 °C

Applicant's summary and conclusion

Conclusions:
A melting point value of -112.16°C is reported as best estimate from 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.
