Oleylamine is an organic compound with a molecular formula C 18 H 35 NH 2. [1] It is an unsaturated fatty amine related to the fatty acid oleic acid.The pure compound is a clear and colorless liquid.
Fatty amines are commonly prepared from fatty acids; which are themselves obtained from natural sources, typically seed-oils.The overall reaction is sometimes referred to as the Nitrile Process [3] and begins with a reaction between the fatty acid and ammonia at high temperature (>250 °C) and in the presence of a metal oxide catalyst (e.g., alumina or zinc oxide) to give the fatty nitrile.
They offer slightly better separation of ethoxylates with varying chain lengths. Common dimensions: 30 m length, 0.25 mm ID, 0.25 μm film thickness. 3. Polar columns (like DB-WAX or HP-FFAP): These are polyethylene glycol (PEG) columns. They are more suited for polar compounds, but Lauryl Alcohol Ethoxylates may still need derivatization.
Fatty alcohol are converted to their ethoxylates by treatment with ethylene oxide: [6] RCH 2 OH + n C 2 H 4 O → RCH 2 (OCH 2 CH 2) n OH. The resulting fatty alcohol ethoxylates are important surfactants. Another large class of surfactants are the sodium alkylsulfates such as sodium dodecylsulfate (SDS).
Oleyl alcohol / ˈ oʊ l i ˌ ɪ l, ˈ oʊ l i əl /, [1] or cis-9-octadecen-1-ol, is an unsaturated fatty alcohol with the molecular formula C 18 H 36 O or the condensed structural formula CH 3 (CH 2) 7 −CH=CH−(CH 2) 8 OH. It is a colorless oil, mainly used in cosmetics.

Narrow-range ethoxylates (NREs) in chemistry are fatty alcohol polyglycol ethers with a narrow homolog distribution and are known nonionic surfactants.They can be produced industrially, for example, by the addition of ethylene oxide onto fatty alcohols in the presence of suitable catalysts (layer compounds which have been calcined or hydrophobized with fatty acids).
