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 ...
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.
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). [1]
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.

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 ...
