Description of key information
Boiling point: HEDP-4Na melts above 500°C.
Key value for chemical safety assessment
Additional information
The boiling point of HEDP-4Na was attempted using a Differential Scanning Calorimetry (DSC) method in accordance with OECD Test Guideline 103. During the study, it was observed that the thermograms show evidence of loss of water at about 103°C and 981 mBar. During the melting point study using same DSC method, HEDP-4Na was observd not to melt below 500°C.
