-vapour density = 3.3
-refractive index nd 20 = 1.1598-1.5261
-refractive index nd 25 = 1.1545-1.5235
-heat of vaporization = 9.22 kcal/mole
-vapour diffusion coefficient (at 25˚C) = 0.087 cm2/s
-conversion factor ( at 25 ˚C and 1013 mbar): 1ppm = 3.93 mg/m3; 1 mg/m3 = 0.254 ppm
-odour treshold = 0.25-1.0 mg/m3
