Product Description

Products Description of Oleic acid CAS# 112-80-1

Oleic acid (CH₃(CH₂)₇CH=CH(CH₂)₇COOH) is the most abundant natural monounsaturated fatty acid, derived from oil and fat hydrolysis. Its glycerides are the main constituent of olive oil, palm oil and lard; industrial grade contains 7–12% saturated fatty acids and trace linoleic acid. A colorless oily liquid, it has defined specific gravity, solidification/boiling points, refractive index, iodine value and acid value as specified.

Product Application of Oleic acid CAS# 112-80-1

Oleic acid is a core industrial organic chemical. It is used to manufacture epoxy oleate plasticizers and azelaic acid resin precursors, and finds applications in pesticide emulsification, mineral processing, industrial cleaning, office supplies and laboratory biochemical/elemental detection reagents.
