Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The study does not need to be conducted because the substance and its relevant degradation products decompose rapidly.

Key value for chemical safety assessment

Additional information

No study was carried out for 1-Butylpyridinium heptachlorodialuminate (CAS 67226-45-3) as the substance hydrolyses very rapidly in contact with water. According to literature systems with chloroaluminate anions must be classified as extremely hygroscopic and labile towards hydrolysis. The aluminium (III) halides are extremely sensitive to even the smallest amounts of water. In the literature it is described that when water is added to chloroaluminate ionic liquid of any composition, an exothermic reaction occurs with the evolution of HCl. This reaction produces oxide- and proton-containing species, both of which can interact with other solutes.
