Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
melting point/freezing point
Type of information:
other: data from OECD SIDS
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: literature not available, the data, however, were evaluated in the frame of the OECD SIDS program and therefore regarded as valid
Principles of method if other than guideline:
data from peer-reviewed database
GLP compliance:
not specified
Type of method:
other: No data
Melting / freezing pt.:
-63 - -17.1 °C
Conclusions:
The melting points of m-diisopropylbenzene and p-diisopropylbenzene are -63°C and -17.1°C, respectively.
Executive summary:
The melting points of m-diisopropylbenzene and p-diisopropylbenzene are reported to be -63°C and -17.1°C, respectively.
Endpoint:

Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: peer-reviewed handbook data
Principles of method if other than guideline:

Type of method:
other: No data
Melting / freezing pt.:
-63.1 °C
Remarks on result:
other: m-diisopropyl benzene
Melting / freezing pt.:
-17 °C
Remarks on result:
other: p-diisopropylbenzene
Conclusions:
The melting points of m- and p-diisopropyl benzene are -63.1 and -17°C, respectively.
Executive summary:

In the peer-reviewed handbook, the melting points of m- and p-diisopropyl benzene are reported to be -63.1 and -17°C, respectively.

Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
other information
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
other: peer-reviewed handbook data, but the melting point reported in respect to p-diisopropylbenzene (+64°C) is in contradiction to the information provided in other reliable sources (-17.1°C) and therefore regarded as invalid
GLP compliance:
not specified
Melting / freezing pt.:
-63 °C
Remarks on result:
other: m-diisopropylbenzene
Melting / freezing pt.:
64 °C
Remarks on result:
other: p-diisopropylbenzene
Conclusions:
The melting points of m- and p-diisopropylbenzene are reported to be -63°C and 64°C, respectively. The reported melting point in respect to p-diisopropylbenzene (+64°C), however, is in contradiction to the information provided in other reliable sources (-17.1°C) and therefore regarded as invalid.
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
other information
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
other: peer-reviewed handbook data, but the melting point reported in respect to m-diisopropylbenzene is significantly lower as the values reported in other reliable sources and therefore regarded as not assignable
GLP compliance:
not specified
Melting / freezing pt.:
-105 °C
Remarks on result:
other: m-diisopropylbenzene
Conclusions:
The melting point of m-diisopropylbenzene is reported to be -105°C. But the melting point reported is significantly lower as the values reported in other reliable sources and therefore regarded as not assignable.
