Description of key information

The boiling point naphthenic acids, zinc salts was determined with 317.5 °C (590.7 K) under decomposition between 99094hPa and 99136hPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
317.5 °C

Additional information

Naphthenic acids, zinc salts became more viscous and had changed its colour to reddish amber with a black residue at the surface after the test which was a clear sign of decomposition.
