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.
In organic chemistry, ethoxylation is a chemical reaction in which ethylene oxide (C 2 H 4 O) adds to a substrate. It is the most widely practiced alkoxylation, which involves the addition of epoxides to substrates. In the usual application, alcohols and phenols are converted into R(OC 2 H 4) n OH, where n ranges from 1 to 10. Such compounds ...
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.
Fatty alcohols are relatively benign materials, with LD 50 (oral, rat) ranging from 3.1–4 g/kg for hexanol to 6–8 g/kg for octadecanol. [1] For a 50 kg person, these values translate to more than 100 g. Tests of acute and repeated exposures have revealed a low level of toxicity from inhalation, oral or dermal exposure of fatty alcohols.
In organic chemistry, amine value is a measure of the nitrogen content of an organic molecule. [1] Specifically, it is usually used to measure the amine content of amine functional compounds. [ 2 ] It may be defined as the number of milligrams of potassium hydroxide (KOH) equivalent to one gram of epoxy hardener resin.
Dectaflur consists of oleyl amine (the amine corresponding to oleyl alcohol) and hydrofluoric acid. Oleyl amine with its long lipophilic hydrocarbon chain has surfactant properties. It forms a film layer on the surface of teeth, which facilitates incorporation of fluoride into the top layers of the enamel, reaching a depth of only a few ...

Oleochemistry is the study of vegetable oils and animal oils and fats, and oleochemicals derived from these fats and oils.The resulting product can be called oleochemicals (from Latin: oleum "olive oil").
