<= Coal tar
is a
black or
brown viscous liquid, also known as coal tar
It is one of the important products of coke< =>chemical industry< = and its output It accounts for about %~% of coal for furnace loading. Its composition is extremely complex. In most cases, it is specially separated and purified by the coal tar industry for use. Each fraction of tar can be further processed to separate a variety of products. The main products currently extracted are: < =>
< => Naphthalene is used to prepare phthalic anhydride for the production of resins, engineering plastics, and dyes. Used in paints and medicines.
< =>
< => Phenol and its homologues are used to produce synthetic fibers, engineering plastics, pesticides, medicines, fuel intermediates, etc.
< =>
< => Anthracene is used to produce anthraquinone fuel, synthetic kneading agents and paints.
< =>
< => The isomer content of phenanthrene anthracene is second only to naphthalene. It has many uses and needs to be further developed and utilized due to its large output.
< =>
< => Carbazole is an important raw material for dyes, plastics, and pesticides.
< =>
< => Asphalt is a mixture of tar distillation residues and a variety of polycyclic polymer compounds. It is used for making roof coatings, moisture-proof layers and road construction, producing < => asphalt coke < => and electric furnace electrodes, etc.
