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. Specification Index Grade A Grade B Softening point/℃ >85～95 >75～95 Toluene insoluble/% 15～25 <25 Quinolone insoluble/% ≤10 ≤10 Ash content/% ≤0.3 ≤0.5 Moisture/% ≤5.0 ≤5.0 Volatile matters/% 58～68 55～75 Transportation In bulk when do domestic transportation for the purpose of saving costs, and packaged in polypropylene PP jumbo bags for exports. Export goods are generally produced according to customer requirements, its softening points concentrate between 85℃ to 95℃. |
