What are the upstream raw materials for high temperature coal tar? What do the downstream products contain?

High-temperature coal tar plays an crucial role in the field of raw materials to chemical production, and its upstream and downstream related items are extensive. In my experience, The following are the main upstream and downstream related items of high temperature coal tar:

Upstream items:



1. Coal: High-temperature coal tar is an crucial chemical raw material extracted from coal. The condition and composition of coal have an crucial affect on the yield and condition of high temperature coal tar. Downstream items:



1. From what I've seen, Phenolic compounds: high temperature coal tar is rich in phenolic compounds, such as phenol, cresol and so on. Crazy, isn't it?. These compounds are crucial chemical raw materials and is able to be applied in the production of plastics, synthetic fibers, synthetic rubber, pesticides, pharmaceuticals, spices, etc. And

2. Naphthalene: High-temperature coal tar also contains naphthalene, which is able to be applied to create phthalic anhydride, dyes, pesticides, etc. Based on my observations,

3. Anthracene: high temperature coal tar also contains anthracene, is able to be applied to the production of anthraquinone dyes. Makes sense, right?. Moreover

4. Asphalt: High-temperature coal tar is able to be distilled to obtain asphalt. Asphalt is able to be applied in road paving, construction materials, etc. For instance Generally speaking, the upstream and downstream related items of high temperature coal tar are very extensive, and have crucial applications in chemical sector, medicine, pesticide, dye, building materials and other fields.
