> 120C

Ignition temperature:

(may be marketed in flammable mixtures)

Solvolysis/solubility:

in water: 24 mg/l at 25C

soluble in most organic solvents: in dichloromethane, 2-propanol, toluene > 200 g/l; in n-hexane 50-100 g/l; very slightly soluble in kerosene and mineral oil

Conversion factors:

1 mg/m3 = 0.083 ppm

1 ppm = 12.106 mg/m3
