Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Sample mass = 8.45mg

An endotherm was recorded between 110 -120°C, corresponding to the melting point.

A strong exotherm was recorded with onset 280°C, and peak at 357°C. The integrated exotherm gave ΔH=1960J/g

Conclusions:
A strong exotherm was noted with onset 280°C and ΔH=1960J/g. The substance is considered to be stable at room temperature according to the criteria set out in OECD Guideline 113 (no decomposition observed <150°C).

Sample mass = 15.30mg

An endotherm was recorded between 115°C, corresponding to the melting point, ΔH=132J/g

A strong exotherm was recorded with onset 295°C, and peak at 357°C. The integrated exotherm gave ΔH=-1900J/g

Conclusions:
A strong exotherm was noted with onset 295°C and ΔH=-1900J/g. The substance is considered to be stable at room temperature according to the criteria set out in OECD Guideline 113 (no decomposition observed <150°C).

Description of key information

Strong exotherm, onset at ca. 280 °C, ΔH=-1960 J/g, OECD 113, DSC, Bailey 2010 
Strong exotherm, onset at ca. 295 °C, ΔH=-1900 J/g, OECD 113, DSC, Bailey 2011
SADT >75 °C, test period 8 days, UN TGD Test H.4, Bailey 2011

Additional information

A strong exotherm was noted with onset at 280 °C and ΔH=-1960 J/g. An endotherm was recorded between 110-120 °C, corresponding to the melting point. A second batch (Bx20100627127, CA3611A) was tested and a strong exotherm was noted with onset at 295 °C and ΔH=-1900 J/g. An endotherm was recorded at 115 °C, corresponding to the melting point. Both data were in good agreement. The substance is considered to be stable at room temperature according to the criteria set out in OECD Guideline 113 (no decomposition observed <150 °C).

The second batch (Bx20100627127, CA3611A) was further tested according to the methods described in the UN Recommendations on Transport of Dangerous Goods to determine the self-accelerating decomposition temperature (SADT). No decomposition was observed over a period of 8 days at 75 °C.

Justification for classification or non-classification

Because the self-accelerating decomposition temperature (SADT) was >75 °C, the substance does not meet the criteria for classification (see Regulation (EC) No. 1272/2008, Annex I, Part 2, section 2.8.2.1 (e)). The available experimental test data are considered reliable, suitable for classification purposes and conclusive.
