Physico/Chemical Properties of DPGDB

  • Appearance/physical state: clear colourless liquid (at room temperature).  
  • Melting point/freezing point: Pour point: -20°C (253K)
  • Boiling point: Not determinable; DPGDB decomposes above 270°C without boiling.
  • Relative density: 1.12
  • Vapour pressure: 0.00016 Pa) at 25°C.
  • Partition coefficient (HPLC method): Log10Pow= 3.9, equivalent Pow = 7.1 x 10
  • Water solubility at pH 7: 8.69 mg/L
  • Surface tension: 59 mN/m
  • Flash point: 192°C at 1006.8 mbar
  • Auto flammability: No ignition temperature below 400°C
  • Explosiveness: Not explosive
  • Oxidising properties: Not oxidising

Note that certain of the determined physico-chemical properties of DPGDB, specifically boiling point, vapour pressure and water solubility, may be influenced to some extent by the impurities present.
