n-Butanol (industrial grade) plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are rich and diverse. The upstream and downstream associated products of n-butanol will be described in detail below.

Upstream Products:

1. Propylene: Propylene is the main raw material for the production of n-butanol, which can be produced by the propylene carbonyl synthesis process.
2. Syngas: Syngas (a mixture of carbon monoxide and hydrogen) can also be used to produce n-butanol by reacting carbon monoxide and hydrogen in syngas.

downstream products:

1. butyl acetate: n-butyl alcohol and acetic acid in the presence of acidic catalyst esterification of butyl acetate, is an excellent organic solvent, widely used in paint, paint, ink and other industries.
2. Butyraldehyde: Butyraldehyde can be obtained by dehydrogenation of n-butanol under acidic conditions. Butyraldehyde is an important chemical raw material for the production of butyric acid, butylamine, nitrile rubber, etc.
3. Butyric acid: Butyric acid can be obtained by further oxidation of butyraldehyde. Butyric acid is an important organic acid used in the production of butyrate, butyrate and so on.
4. Butylamine: Butylamine can be obtained by the reaction of butyraldehyde and ammonia. Butylamine is an important organic amine used in the production of rubber accelerators, preservatives, antioxidants, etc.
5. Ester plasticizer: n-butanol can be used to produce ester plasticizer, such as dibutyl phthalate, widely used in plastics, rubber and other industries.

In short, n-butanol plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are extensive, involving many fields, such as coatings, inks, plastics, rubber, etc.
