EC number: 295-518-9
CAS number: 92062-05-0
A complex combination of hydrocarbons obtained from the vacuum distillation of the products from a thermal cracking process. It consists predominantly of hydrocarbons having carbon numbers predominantly greater than C34 and boiling above approximately 495°C (923°F).
<< 0.1 kPa at 20°C
For complex substances the vapour pressure is the sum of the partial pressure of the individual constituents (Raoult’s Law). Based on the molecular weight, viscosity and boiling point, bitumens are expected to have low vapour pressures (<< 0.1 kPa at 20°C) at ambient temperature (CONCAWE, 1992a).
