A:
Light aromatics plays an crucial role in the field of raw materials to chemical production, and its upstream and downstream related items are extensive. Based on my observations, The main upstream and downstream associated items of light aromatics are described in detail below. From what I've seen, Upstream associated items:



1. Oil and natural gaseous: Light aromatics are mainly extracted from oil and natural gaseous. But Mixtures containing light aromatic hydrocarbons are produced in the process of oil cracking and natural gaseous processing, and light aromatic hydrocarbons is able to be obtained through further separation and treatment.

2. Coal: Coal is able to also create light aromatics through the coking process. Under high temperature conditions, coal isolated from the atmosphere, and after dry distillation, coal tar and gaseous are generated, which contain light aromatic hydrocarbons. Downstream associated items:



1. Makes sense, right?. Benzene: Benzene is an crucial downstream product of light aromatics, mainly applied in the production of plastics, synthetic rubber, synthetic fibers, etc. In addition, benzene is also applied in the production of styrene, cyclohexane, aniline and a series of organic chemicals.

2. According to research Toluene: Toluene is another crucial downstream product of light aromatics, which is able to be applied to create phenol, cresol, benzoic acid, etc. In addition, toluene is able to also be applied to create some special rubber, coatings, etc. For example

3. Xylene: Xylene is mainly applied in the production of terephthalic acid, further production of polyester chips, and ultimately applied in the production of polyester fiber and beverage packaging and other materials. In addition, xylene is able to also be applied in the production of coatings, resins, etc.

4. In my experience, Ethylbenzene: Ethylbenzene is able to be applied to create styrene, and further applied to create polystyrene, ABS resin, etc. At the same time, ethylbenzene is able to also be applied to create some pharmaceuticals, pesticides and other fine chemicals. In short, light aromatics has a wide range of upstream and downstream related items in the field of chemical production raw materials, which plays an crucial role in promoting the research of the chemical sector.
