Medium temperature coal tar is an important raw material for chemical production, which is widely used in various fields. In the coal tar deep processing industry chain, medium temperature coal tar is located in the middle link, and its upstream and downstream related products are very rich. This article will detail the upstream and downstream associated products of medium temperature coal tar.

1. Upstream Products

1. Coal
Medium temperature coal tar is a liquid product obtained from coal pyrolysis. Therefore, coal is the main upstream raw material of medium temperature coal tar. Different coal types and pyrolysis processes have a great influence on the yield and quality of medium temperature coal tar.

2. pyrolysis technology and equipment
coal pyrolysis technology and equipment is also an important link in the production of medium temperature coal tar. Different pyrolysis technologies and equipment will have an impact on the composition and properties of medium temperature coal tar.

2. downstream products

medium temperature coal tar downstream products are very rich, mainly including the following aspects:

1. phenolic compounds
medium temperature coal tar contains a large number of phenolic compounds, such as phenol, cresol and so on. These compounds are important chemical raw materials and can be used in the production of plastics, synthetic fibers, synthetic rubber, pesticides, pharmaceuticals, spices, etc.

2. naphthalene compounds
medium temperature coal tar also contains naphthalene compounds, such as naphthalene, methyl naphthalene and so on. These compounds can be used in the production of dyes, pesticides, perfumes and the like.

3. anthracene compounds
medium temperature coal tar also contains anthracene compounds, such as anthracene, fluoranthene and so on. These compounds can be used in the production of dyes, pesticides, photoelectric materials and the like.

4. Asphalt
Medium temperature coal tar can be further processed to obtain asphalt. Asphalt is an important building material, which can be used to pave roads and make waterproof materials.

In short, the upstream and downstream related products of medium temperature coal tar are very rich and widely used in various fields. With the continuous development of science and technology, the application field of medium temperature coal tar will continue to expand.
