Product Description of Oleic Acid (CAS# 112-80-1)
Oleic acid is an unsaturated fatty acid characterized by a carbon-carbon double bond in its molecular structure. As a constituent of olein, it is the most abundant natural unsaturated fatty acid. It is derived through the hydrolysis of oils and fats, with the chemical formula CH3(CH2)7CH=CH(CH2)7COOH.
Oleic acid glycerides are a primary component of olive oil, palm oil, lard, and other animal and plant oils. Industrial-grade oleic acid typically contains 7-12% saturated fatty acids (including palmitic and stearic acids) and trace amounts of other unsaturated fatty acids (such as linoleic acid).
Physically, it appears as a colorless oily liquid with a specific gravity of 0.895 (at 25/25°C), a solidification point of 4°C, and a boiling point of 286°C (under 13,332 Pa pressure). Additional properties include a refractive index of 1.463 (at 18°C), an iodine value of 89.9, and an acid value of 198.6.
