(S)-1,2-epoxypropane

Melting point / freezing point

Administrative data

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2002

Reliability:

Test material

Test material information

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 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.
