Endpoint:
melting point/freezing point
Type of information:
other: presumably experimental
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
Peer reviewed data from HSDB (referring to Lide, D.R. (ed.), 1998-1999). HSDB database is referred to as reliable source in Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, Table R.7.1-2 Sources of physico-chemical data.
Principles of method if other than guideline:
no information on the conducted test procedure
GLP compliance:
not specified
Type of method:
other: no data
Melting / freezing pt.:
-43 °C
Conclusions:
The melting point of the test substance diethyl carbonate has been determined to be -43 °C.
Endpoint:
melting point/freezing point
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
Accepted encyclopedia for a wide range of chemicals, drugs and biologicals; no information on the conducted test procedure. The Merck Index is referred to as reliable source in Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, Table R.7.1-2 Sources of physico-chemical data.
Principles of method if other than guideline:
No information on the conducted test procedure
GLP compliance:
not specified
Type of method:
other: no data
Melting / freezing pt.:
-43 °C
Conclusions:
The melting point of the test substance diethyl carbonate has been determined to be -43 °.
Endpoint:
melting point/freezing point
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Hawley’s Condensed Chemical Dictionary is referred to as reliable source in Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, Table R.7.1-2 Sources of physico-chemical data.
Principles of method if other than guideline:
no information on the conducted test procedure
GLP compliance:
not specified
Type of method:
other: no data
Melting / freezing pt.:
-43 °C
Conclusions:
The value of the melting point for the test substance diethyl carbonate is -43 °C.
Endpoint:
melting point/freezing point
Adequacy of study:
disregarded due to major methodological deficiencies
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
Sax’s Dangerous Properties of Industrial Materials is referred to as reliable source in Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, Table R.7.1-2 Sources of physico-chemical data. Obviousely an error occurred according to the value of the melting point.
GLP compliance:
not specified
Type of method:
other: no data
Melting / freezing pt.:
43 °C
Remarks on result:
other: no information on pressure; since the test substance is a liquid obviousely the given melting point is wrong (probably -43 °C)
Conclusions:
The given melting point (43 °C) of the test substance diethyl carbonate is obviousely wrong as the substance is a liquid. Presumably the value is -43 °C.
