  Specification:
  
  1. Definitiona:lso called medium temperature pitch is tar distillation residual liquid part, the yield of tar 54 ~ 56%, it is made up of tricyclic more aromatic compounds and oxygen, nitrogen, and sulfur containing heterocyclic compounds and a small amount of polymer carbon composition. Asphalt components of the molecular weight between 200 and 2000, highest can amount to 3000. Medium temperature pitch is according to the softening point of the different division. Softening point is 65 ~ 90 °C for medium temperature pitch.
  
  2. Property and technical data : The physical and chemical properties and original tar properties and distillation conditions about. The normal temperature of asphalt is black solid, softening point is 65 ~ 90 °C. asphalt is coal tar continuous distillation residual liquid part, yield is 54 ~ 56%, so in the production of industrial naphthalene produces in the process, etc.
