DIBUTYL PHOSPHATE

ICSC: 1278

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID. Physical dangers Chemical dangers Decomposes on heating and on burning. This produces toxic and corrosive fumes including phosphoric acid. The substance is a medium strong acid. Reacts with strong oxidants. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001).	Formula: (CH₃(CH₂)₃)₂HPO₄ / C₈H₁₉PO₄ Molecular mass: 210.2 Boiling point: 135-138°C Melting point: -13°C Relative density (water = 1): 1.06 Solubility in water, g/100ml at 20°C: 1.8 Vapour pressure, kPa at 20°C: 0.13 Relative vapour density (air = 1): 7.2 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.01 Flash point: 188°C o.c. Auto-ignition temperature: 420°C Octanol/water partition coefficient as log Pow: 0.6-1.4
