Distillation fractions of crude coal tar are obtained at various temperatures and include light oil (up to 180 °C), middle oil (180–230°), heavy oil (230–270°), anthracene oil (270–400°), tar fraction (400–600°), and pitch which is the final and most abundant residue (L’Epee et al. 1983; Adams 1990). Pitch, which is usually solid at room temperature, can be produced to a specific softening point between 90 °C and 165 °C. Manufacturing applications of coal tar pitch (CTP) include its use in briquettes, roofing pitch, artificial asphalt, electrodes as a dielectric, adhesives for bonding insulating panels in cold stores, brushes for electric motors or activated carbon, waterproofing materials for wood, dyestuffs, paints, acid-resistant coatings, extenders when blended with various resins and elastomers, saturants for felt, impregnants in the manufacture of carbon products, and ‘clay’ targets for skeet shooting (L’Epee et al. 1983; Anonymous 1997).
