klassifikasie

Gebruike / Function

• "Adipic acid is used in large quantities for the manufacture of nylon." 1

• "Manuf[acture] artificial resins, plastics (nylon), urethan foams. Used as acidulant in baking powders instead of tartaric acid, cream of tartar, and phosphates because adipic acid is not hygroscopic. As an intermediate in lubricating oil additives." 2
