Neopentyl glycol (NPG) is an important organic chemical raw material, which is widely used in the production of various chemicals. The following are the upstream and downstream related products of neopentyl glycol:

Upstream products:

1. Isobutyraldehyde: Isobutyraldehyde is one of the main raw materials of neopentyl glycol, which is produced by hydrogenation reaction.
2. Formaldehyde: Formaldehyde is also an important raw material for neopentyl glycol, which reacts with isobutyraldehyde to generate neopentyl glycol.

downstream products:

1. Polyester resin: Neopentyl glycol can react with dibasic acid to generate polyester resin, which is used in the manufacture of coatings, adhesives, insulating materials, etc.
2. Polyurethane: Neopentyl glycol can be used as a raw material for polyurethane and react with diisocyanate to produce polyurethane for the manufacture of foams, elastomers, etc.
3. Plasticizer: Neopentyl glycol can be used to produce plasticizers, such as phthalic acid two neopentyl ester, used to improve the processing performance and flexibility of plastics.
4. Stabilizer: Neopentyl glycol can be used to produce heat stabilizers and light stabilizers to improve the heat resistance and light resistance of polymer materials such as plastics and rubber.

In short, neopentyl glycol, as an important organic chemical raw material, 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.
