Gasoline is an important raw material for chemical production, which is widely used in transportation, industrial production and other fields. In the chemical production chain, the upstream and downstream related products of gasoline are very rich. This article will detail the upstream and downstream associated products of gasoline.

1. the upstream associated products of gasoline

1. crude oil

the main upstream associated products of gasoline is crude oil. Crude oil is a kind of natural oil extracted from the ground. After refining and processing, various petroleum products and chemical raw materials can be obtained, including gasoline.

2. Naphtha

Naphtha is a light fraction obtained during the distillation of crude oil and is an important upstream related product of gasoline. Naphtha is mainly composed of hydrocarbons. After further processing and treatment, high quality gasoline can be obtained.

2. the downstream associated products of gasoline

1. Ethylene

gasoline can be obtained by cracking reaction. Ethylene is an important chemical raw material, which can be used to produce polyethylene, ethylene propylene rubber, ethylene glycol and other chemical products.

2. Aromatic

gasoline contains a certain amount of aromatic compounds, such as benzene, toluene, xylene, etc. These aromatic compounds can be used as chemical raw materials for the production of plastics, synthetic fibers, dyes and other chemical products.

3. Butadiene

Butadiene is an important chemical raw material, which can be separated from C4 fraction in gasoline. Butadiene is mainly used in the production of synthetic rubber, styrene-butadiene rubber and other chemical products.

4. Propylene

Propylene is a light olefin that can be separated from the pyrolysis gas in gasoline. Propylene can be used to produce polypropylene, acrylic acid and other chemical products.

In short, gasoline plays a connecting role in the chemical production chain, and its upstream and downstream related products are very rich. Through the deep processing and processing of gasoline, we can get a variety of important chemical products and raw materials, and make an important contribution to the development of the national economy.
