Main: India castor oil refinery level, Inner Mongolia refined level of oleic acid and nitric acid castor oil is isomerized to the trans isomer, elaidic a melting point of 44 ~ 45 ℃; hydrogenation is stearate ; using potassium permanganate oxidation mixture is too positive azelaic acid and azelaic acid. Oleic acid, castor oil because it contains a double bond, can occur when the air for a long place from oxidation, partial into carbonyl-containing substances, the rancid smell of corruption, which is the cause of oil deterioration. Commodity oleic acid, typically with 7% to 12% of saturated fatty acids, such as palmitic acid and stearic acid. Sodium or potassium salts of oleic acid soaps is one of the ingredients.
