Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

In reality the self-ignition temperature of aluminium tri-sec-butylate is impossible to determine as the substance hydrolyses in moist air immediately to form 2-butanol and thus the 2-butanol auto ignition temperature determines the result. Two separate TGD-approved handbooks agree that 2-butanol has an auto ignition temperature of 405 °C and thus this value as taken forward as worst case surrogate for hazard and risk assessment of aluminium tri-sec-butylate.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
405 °C

Additional information

Information regarding auto flammability of SBA was sourced from CRC Handbook of Chemistry and Physics (81st Ed) and Fire Protection Guide to Hazardous Materials (13th Ed), which are known to contain peer-reviewed data of Klimisch-2 reliability. Based on the information obtained from the aforementioned handbooks, the substance 2-butanol which forms from aluminium tri-sec-butylate in contact with moisture has an auto ignition temperature of 405 °C. This value represents the lowest temperature at which vapours of SBA will spontaneously ignite in a normal atmosphere without an external source of ignition and thus can be used as worst case surrogate for aluminium tri-sec-butylate. No information on atmospheric pressure was reported.
