Product DetailsProducts Description of Octadecenoic Acid CAS#112-80-1Insoluble in water, soluble in benzene, chloroform, miscible with methanol, ethanol, ether and carbon tetrachloride. Because it contains double bonds, it is easily oxidized by air, producing an unpleasant odor and turning yellow. When treated with nitrogen oxides, nitric acid, mercurous nitrate and sulfurous acid, it can be converted into oleic acid. When hydrogenated, it becomes stearic acid. The double bonds can easily react with halogens to form halogenated stearic acid.
