Reference

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

From July 30, 2018 to August 1, 2018

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study with acceptable restrictions

Qualifier:

according to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Type of method:

differential scanning calorimetry

Melting / freezing pt.:

> 400 °C

Evaporation, reaction and/or decomposition of the test substance were observed during heating: melting of CR SR94 was not observed below the temperature at which evaporation, reaction and/or decomposition started.

Conclusions:

According to OECD 102, the melting temperature of CR SR94 is >400 degree.

Executive summary:

The determination of the melting temperature of CR SR94 was performed in accordance with OECD 102. Differential scanning calorimetry (DSC) was used. Evaporation, reaction and/or decomposition of the test substance were observed during heating: melting of CR SR94 was not observed below the temperature at which evaporation, reaction and/or decomposition started. Therefore CR SR94 has no melting temperature.

Description of key information

The melting temperature of CR SR94 is > 400 ℃.

Key value for chemical safety assessment
