Mixed butanol plays an important role 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 mixed butanol in detail, including upstream raw materials, downstream products and production process.

1. upstream raw materials

mixed butanol upstream raw materials mainly include butene, butyraldehyde and other hydrocarbons. These raw materials are mainly obtained through petrochemical processes, such as cracking petroleum hydrocarbons to obtain butene.

2. the production process of mixed butanol

The production of mixed butanol is mainly realized by aldol method, ethylene method and fermentation method. Among them, the aldol method is the most common production method, mainly through the addition reaction of butyraldehyde and hydrogen under the action of a catalyst to generate mixed butanol.

3. downstream products

mixed butanol as an important organic chemical raw material, its downstream products are extensive, involving many fields. The following are some of the main downstream products:

1. Plasticizer: Mixed butanol can be used to produce plasticizers, such as dibutyl phthalate. Plasticizers are mainly used in plastic processing, which can increase the flexibility and ductility of plastics.
2. Solvent: Mixed butanol can be used as a solvent for coatings, inks, cleaning agents and other fields. Because of its good solubility and volatility, it has a wide range of applications in industrial production.
3. Synthetic rubber: Mixed butanol can be used in the production of synthetic rubber, such as styrene-butadiene rubber, nitrile rubber, etc. These synthetic rubbers are widely used in tires, hoses, tapes and other fields.
4. Surfactant: Mixed butanol can be used as a surfactant raw material for the production of detergents, emulsifiers, etc. Surfactants play an important role in industrial production, which can help to achieve the functions of emulsification, dispersion and wetting of liquids.

In short, mixed butanol has a wide range of upstream and downstream related products in the field of chemical production raw materials, involving many fields. The production process needs to consider factors such as the acquisition of raw materials, the optimization of the production process, and the demand for downstream products in order to maximize the economic and social benefits of production.
