n-Butanol has an important position in the field of chemical production raw materials, and its upstream and downstream related products are extensive. This paper will introduce the upstream and downstream related products of n-butanol in detail, including upstream raw materials, downstream products and production process.

1. upstream raw material

1. Butene: Butene is the main raw material for the production of n-butanol, which can be produced by the hydration reaction of butene.
2. Natural gas: Natural gas contains a large amount of methane, which can be produced by cracking reaction to produce butene, and then used to produce n-butanol.

2. the production process of n-butanol

The production of n-butanol mainly adopts the butene hydration method, which reacts butene with water at a certain temperature and pressure to generate n-butanol and by-products. The reaction equation is as follows:
The reaction conditions need to be controlled in the production process of
C4H8 H2O → C4H9OH

to improve the selectivity and yield of n-butanol. In addition, by-products need to be separated and purified to obtain high purity n-butanol products.

3. downstream products

n-Butanol as an important organic chemical raw materials, widely used in various fields, its downstream products are:

1. Butyl acetate: n-butanol and acetic acid in the acid catalyst esterification of butyl acetate, which is an important solvent and perfume.
2. Butyraldehyde: Butyraldehyde is dehydrated under acidic conditions to produce butyraldehyde, which is an important chemical raw material and can be used to produce plastics, rubber, medicine and other products.
3. Butyric acid: n-Butanol can be oxidized to produce butyric acid, which is a food additive and flavor.
4. Butylamine: n-Butanol reacts with ammonia at high temperature and high pressure to produce butylamine, which is an important organic amine compound and can be used to produce rubber accelerators, preservatives, etc.

4. the market application of n-butanol

n-butanol is widely used in the market, mainly used in the production of coatings, inks, adhesives, plastics, rubber, medicine, spices and other products. Among them, coatings and inks are the largest consumption areas of n-butanol. Due to its good solubility and volatility, n-butanol has become one of the important solvents in coatings and inks.

In addition, n-butanol can also be used for the production of environmentally friendly solvents, cleaning agents, paint removers and other products. With the continuous improvement of environmental awareness, n-butanol is more and more widely used in the field of environmental protection. The upstream and downstream industrial association

the upstream and downstream industries of n-butanol are closely related, and the price and supply of upstream raw materials have an important impact on the production cost and market price of n-butanol. At the same time, the demand for downstream products of n-butanol also directly affects the market demand and price trend of n-butanol. Therefore, strengthening the communication and cooperation between upstream and downstream industries is of great significance for stabilizing the supply of n-butanol market and promoting industrial development. The future development trend of

With the continuous progress of science and technology and the improvement of environmental awareness, the future development of n-butanol will pay more attention to environmental protection, high efficiency and safety. In the future, the production technology of n-butanol will continue to improve, and energy consumption and pollutant emissions will be further reduced. At the same time, the application field of n-butanol will continue to expand, especially in the fields of environmental protection and new energy.

In short, n-butanol has an important position in the field of chemical production raw materials, and its upstream and downstream related products are extensive. Strengthening the communication and cooperation between upstream and downstream industries and improving production efficiency and technical level will help stabilize the supply of n-butanol market and promote industrial development.
