Coal tar distillates are derived from the distillation of coal tars at coal tar refinery facilities. They are made of complex combinations of compounds mainly aromatic hydrocarbons. Their composition varies based on their source the heating temperature and the distillation temperature for the distillates.

Coal-tar pitch is a thick black liquid that remains after the distillation of coal tar. It is used as a base for coatings and paint in roofing and paving and as a binder in asphalt products. Both coal tar and coal-tar pitch contain many chemical compounds including carcinogens such as benzene.

Coal tar principal liquid product resulting from the carbonization of coal i.e. the heating of coal in the absence of air at temperatures ranging from about 900 to 1 200 °C (1 650 to 2 200 °F). Many commercially important compounds are derived from coal tar. Low-temperature tars result when

destructive distillation Process in which a solid material (usually coal or wood) is heated at high temperature out of contact with air to make coke coal tar or charcoal. It is called destructive because the chemical composition of the end product is distinctly different from that of the input material. See also fractional distillation.

Coal tars and coal-tar pitches have many uses in industry and in con-sumer products. Coal tars are used primarily for the production of refined chemicals and coal-tar products such as creosote coal-tar pitch and crude naphthalene and anthracene oils from the distillation of crude coal tar. Coal tar has been used as a fuel in open-hearth fur-

Tests were made to determine the proportion of residue necessary to enable coal tar creosote to impart its maximum protection to wood. This was done by exposing a series of wooden panels impregnated with creosotes containing varying percentages of residue to marine borer attack and determining their relative degree of resistance.

Distillates are made up of crude coke oven tar components which are produced during the high temperature coking of bituminous coal. Carbon pitch boils between 100°C and 400°C during the distillation process. Refined chemical oil distills between 210°C and 315°C.
