Chemical compound

Neopentyl glycol (IUPAC name 2,2-dimethyl-1,3-propanediol) is an organic chemical compound. It is used in the sythesis of polyesters, paints, lubricants, and plasticizers. When used in the manufacture of polyesters, it enhances the product's stability toward heat, light, and water.

Reactions

Neopentyl glycol is synthesized industrially by the aldol reaction of formaldehyde and isobutyraldehyde. This creates the intermediate hydroxypivaldehyde, which can be converted to neopentyl glycol with either excess formaldehyde or catalytic hydrogenation of the aldehyde group to an alcohol group.
