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, 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. The units are thus mg KOH/g.
Toxicity to certain invertebrates has a range of EC50 values for linear AE from 0.1 mg/L to greater than 100 mg/L. For branched alcohol exthoxylates, toxicity ranges from 0.5 mg/L to 50 mg/L. [ 15 ] The EC50 toxicity for algae from linear and branched AEs was 0.05 mg/L to 50 mg/L. Acute toxicity to fish ranges from LC50 values for linear AE of ...
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 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).
