| [Features]
Behenic acid(112-85-6), is a normal carboxylic acid.
At 9%, it is a major component of Ben oil (or behen oil), which is extracted from the seeds of the Ben-oil tree. It is so named from the Persian month Bahman when the roots of this tree were harvested.
Behenic acid(112-85-6) is also present in some other oils and oil-bearing plants, including rapeseed (canola) and peanut oil and skins. It is estimated that one ton of peanut skins contains 13 pounds of behenic acid. Commercially, behenic acid is often used to give hair conditioners and moisturizers their smoothing properties.
As a dietary oil, behenic acid is poorly absorbed. In spite of its low bioavailability compared with oleic acid, behenic acid is a cholesterol-raising fatty acid in humans.
Reduction of behenic acid yields behenyl alcohol. | [Melting point ]

| Questions And Answer | Back Directory | [Preparation]
Docosanoic acid can be prepared in several ways, the most common being direct extraction, specifically from shea butter and palm kernel oil. The preparation process mainly consists of two parts: First, raw material extraction: shea butter or palm kernel oil is refined and hydrogenated to remove impurities, then purified by distillation or extraction. Second, refining: the extracted Docosanoic acid is further purified using vacuum distillation and crystallization techniques. |

ChEBI: A straight-chain, C22, long-chain saturated fatty acid. | [Description]
Docosanoic acid is a straight-chain, C22, long-chain saturated fatty acid. It has a role as a plant metabolite. It is a straight-chain saturated fatty acid and a long-chain fatty acid. It is a conjugate acid of a behenate. | [General Description]
Monomolecular films of stearic and behenic acid were formed on substrates 0.1M in sodium chloride, sodium bicarbonate or sodium phosphate and were investigated by IR analysis. | [Flammability and Explosibility]
Nonflammable | [Source]
Docosanoic acid is present in some oils and oil-bearing plants, including rapeseed (canola) and peanut oil and skins. It is estimated that one ton of peanut skins contains 13 pounds (5.9 kg) of docosanoic acid. | [storage]
