Hydrocarbons, C6, isoalkanes, <5% n-hexane

Melting point / freezing point

Link to relevant study record(s)

Reference

Endpoint:

melting point/freezing point

Type of information:

read-across from supporting substance (structural analogue or surrogate)

Adequacy of study:

key study

Study period:

Up to 2008

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: GLP status not known, guideline not known, information from a published handbook, acceptable with restrictions.

Justification for type of information:

A discussion and report on the read across strategy is given as an attachment in IUCLID Section 13.

Reason / purpose for cross-reference:

read-across: supporting information

Principles of method if other than guideline:

The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to the CRC Handbook of Chemistry and Physics states that data for physical constants have been taken from many sources, including both compilations and the primary literature. Where conflicts were found, the value deemed most reliable was chosen. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.

GLP compliance:

no

Remarks:

litterature

Type of method:

other: no data reported.

Key result

Melting / freezing pt.:

-153.6 °C

Atm. press.:

101.3 kPa

Decomposition:

no

Sublimation:

no

Remarks on result:

other: Standard pressure assumed.

Conclusions:

The melting point of Iso-Hexane is -153.6°C.

Executive summary:

The melting point of Iso-Hexane has been taken from the CRC Handbook. No information on the primary source of this data or the methods used is available. However, this information is taken from a reliable peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint.

Description of key information

The pour point for Hydrocarbons, C6, isoalkanes,  <5% n-hexane  is <-20°C

Additional information

The pour point for Hydrocarbons, C6, isoalkanes,  <5% n-hexane is <-20°C based on the methodology ASTM D 5950.This range has been agreed by the consortium to represent the substance.

There is no data available for Hydrocarbons, C6, isoalkanes, <5% n-hexane. However, data is available for a structural analogue, isohexaneand presented in the dossier. This data is read across toHydrocarbons, C6, isoalkanes, <5% n-hexane based on analogue read across and a discussion and report on the read across strategy is provided as an attachment in IUCLID Section 13.

The melting point of Isohexane is -153.6°C.
