1,6-Hexanediol (1,6-Hexanediol) is an important chemical raw material, widely used in plastics, fibers, coatings, pharmaceuticals and other fields. The following are the upstream and downstream related products of 1,6-hexanediol:

upstream products:

1. Adipic acid: Adipic acid is one of the important raw materials for the production of 1,6-hexanediol. Adipic acid is generated through esterification reaction, and then 1,6-hexanediol is obtained through hydrogenation reaction.
2. Ethylene oxide: Ethylene oxide reacts with ethylene glycol to produce ethylene glycol diethyl ether, which can be hydrogenated to obtain 1,6-hexanediol.

downstream products:

1. polyester resin: 1,6-hexanediol and terephthalic acid reaction to generate polyester resin, commonly used in the production of beverage bottles, films and other plastic products.
2. Polyurethane: 1,6-hexanediol reacts with diisocyanate to produce polyurethane, which is commonly used in the production of foams, elastomers, coatings, etc.
3. Plasticizer: 1,6-Hexanediol can be used to produce plasticizers, such as dihexyl phthalate, etc., to improve the processing performance and flexibility of plastics.
4. Pharmaceutical intermediates: 1,6-hexanediol can be used as pharmaceutical intermediates for the production of some drugs, such as anti-tuberculosis drugs.

In short, 1,6-hexanediol, as an important chemical raw material, has a wide range of applications in the field of chemical production, and its upstream and downstream related products are also very rich.
