• Detailed Description:

  Cas No. :8052-42-4 Physical and Chemical properties
  Medium-temperature coal tar pitch is the mixture of polycyclic aromatic hydrocarbons and polymer resin, which contains oxygen, nitrogen, and sulfur heterocyclic compound and a small amount of polymer carbon substance. It is also the residue after the 360℃ distillation, solidified into the elongated particles(1-5cm) in a fragile shell-shape glass looking under specific temperature without thermal effect. It is black fragile lumps under room-temperature, and can be converted into liquid when heating, with characteristic of shiny look, toxic in a slight odor. Its boiling point is no higher than 470℃ and flash point is 204.4℃. Melting point around 75-95℃, 1.25-1.35g/cm3. Its production accounts for 50%-60% of coal tar.
