Description of key information

Tartaric acid and its salts have boiling points higher than 100°C.

According to literature and experimental data, the boiling point ranges between 130 and 600 °C.

Key value for chemical safety assessment

Additional information

A collection of the boiling point values was performed for tartaric acid and its salts (i.e. monosodium, monopotassium, sodium potassium, sodium, potassium and calcium tartrate). All found values are listed below.
