Link to relevant study record(s)
- 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.
