n-Heptane has an important position in the field of chemical production raw materials, and its upstream and downstream related products are extensive. The following are some of the main upstream and downstream associated products:

1. Upstream products: The production of
n-heptane mainly depends on processes such as oil cracking and natural gas fractionation. Therefore, the upstream products of n-heptane mainly include oil and natural gas. In addition, n-heptane can also be obtained by purification of biodiesel by-products, and thus biodiesel by-products are also one of the upstream products of n-heptane.

2. Downstream products:
n-Heptane, as an important organic solvent and chemical raw material, is widely used in various fields. Therefore, there are many downstream products of n-heptane, and some of the main downstream products are listed as follows:
(1) octane improver: n-heptane can be used as an octane improver to improve the octane number of gasoline, thereby improving the combustion performance of gasoline.
(2) solvent: n-heptane is an excellent solvent, can be used for cleaning, extraction, separation and other chemical processes.
(3) Rubber and plastics: n-heptane can be used as a raw material for the production of rubber and plastics for the manufacture of various rubber and plastic products.
(4) Coatings and inks: n-Heptane can be used as solvents and diluents for coatings and inks, and is used to adjust the viscosity and drying properties of coatings and inks.

In short, n-heptane has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related products are also very rich.
