Coal tar distillate (of which creosote is a product) is a dark brown liquid that is produced by thermal distillation of coal tar. Coal tar is a biproduct of producing coke for steel production from coal via a pyrolytic process in "coke ovens" where the coal is heated to over 1,000°C in an oxygen-limited condition (Ametek 2022).The tar is distilled into …

Coal tar distillates result from the distillation of coal tars at coal tar refinery facilities. All coal tar compounds are considered to be substances of Unknown or Variable composition, Complex reaction products, or Biological materials (UVCBs). They are made of complex combinations of compounds, mainly aromatic hydrocarbons.

Fractional distillation is one of the popular separation techniques used in several industries. While the principle behind the process remains the same, the distillation is carried out on a larger scale. Usually, huge vertical cylindrical columns are known as "distillation columns" or "distillation or fractionation towers" are used.

Process of destructive distillation: In this process, coal is taken in a test tube and heated. Coal breaks down to produce coke, coal tar, ammonia and coal gas. Coal tar is collected at the bottom of the other test tube and coal gas escapes out of it. Ammonia is absorbed in water which forms ammonia liquor [N{H_4}OH].
