As an important chemical raw material, n-heptanol is widely used in chemical industry. Its upstream and downstream related products are numerous, mainly involving alcohols, acids, esters, ketones, ethers and a series of organic compounds. The following will introduce in detail the upstream and downstream associated products of n-heptanol.

1. Upstream product

(1) Propylene: Propylene is one of the main raw materials for the production of n-heptanol, which can be produced by the carbonylation reaction of propylene.

(2) Hydrogen: Hydrogen is used as a reducing agent in the production process of n-heptanol and participates in the reduction reaction.

(3) Catalyst: The production process of n-heptanol requires the use of catalysts, such as rhodium, ruthenium and other noble metal catalysts, to improve reaction efficiency and selectivity.

2. Downstream product

(1) n-heptanoic acid: n-heptanol can generate n-heptanoic acid through oxidation reaction, which is an important organic acid that can be used to produce plasticizers, fragrances, etc.

(2) n-heptanal: n-heptanol can be dehydrogenated to generate n-heptanal, which is an important chemical intermediate that can be used to produce drugs, pesticides, etc.

(3) n-heptyl ester: n-heptanol can be esterified with acids or acid chloride compounds to generate n-heptyl ester, such compounds can be used as solvents, plasticizers and the like.

(4) n-heptanone: n-heptanol can be ketonized to produce n-heptanone, which is an important solvent and organic synthesis intermediate.

(5) ethyl n-heptyl ether: n-heptanol can be etherified with alcohol compounds such as ethanol to generate ethyl n-heptyl ether, which can be used as solvents, fragrances and the like.

In short, as an important raw material for the production of chemical products, n-heptanol has a wide range of upstream and downstream related products and involves a wide range of compounds. These products are widely used in chemical, pharmaceutical, pesticide, spice and other fields.
