Description
A white crystalline, solid that occurs naturally in beet juice. Adipic acid is prepared synthetically from cyclohexanol. It is primarily used in the production of Nylon and Polyurethane foams. Adipic acid is also used as a Plasticizer, Lubricant, and a food additive in baking powder (in place of Cream of tartar) and in beverages (in place of Citric acid). It is not Hygroscopic. Prior to 1940, adipic acid was also used for bronzing metals, preparing photographic paper, textile dyeing, and as a component in synthetic wax sizes mixed with Glycerol, Stearic acid, and Palmitic acid. Adipic acid may evolve from degraded polyurethane ester-type foams (Tétreault 2017).
