Conclusions:
Self ignition temperature for CAS No 101316-62-5 was determined as 505 Degs C at unknown pressure.
Executive summary:

Information was provided by individual companies in the form of a letter stating the relevant information. The letter was submitted in company’s headed paper and signed by the individual responsible for the area of work. Given that the companies have practical expertise in handling the substance/stream this was deemed to be acceptable information.

Self ignition temperature for CAS No 101316-62-5 was determined as 505 Degs C at unknown pressure.

Description of key information

Autoflammability data are available for 2 streams within this category ranging from 409 to 505°C.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
457 °C

Additional information

The autoflammability values for streams in this category have been taken from proprietary data and certificates of analysis.

CAS# 94733-07-0: 409°C (BASF, 2007b); CAS# 101316-62-5: 505°C (Rutgers, 2010b).

These data will be read across to all category members.

The mean autoflammability value is 457°C and this has been used to complete the ‘key value for chemical safety assessment’.
