Description of key information

Bis(2-ethylhexyl) hydrogen phosphate decomposes below the boiling point at 240°C at 1013 hPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
240 °C

Additional information

In an experiment, it was shown that bis(2-ethylhexyl) hydrogen phosphate decomposes below the boiling point at 240°C. The original report is not available, but it is reported that the boiling point of bis(2-ethylhexyl) hydrogen phosphate was determined by Differential thermo analysis (DTA) at a heating rate of 5°C/min in a glass ampule.

Further, several data on the boiling point are available for bis(2-ethylhexyl) hydrogen phosphate. But as they are obtained at pressures of 0.015 hPa and 10 hPa, they are not relevant for assessment.
