Ethoxylated fatty alcohols are often converted to the corresponding organosulfates, which can be easily deprotonated to give anionic surfactants such as sodium laureth sulfate. Being salts, ethoxysulfates exhibit good water solubility (high HLB value). The conversion is achieved by treating ethoxylated alcohols with sulfur trioxide. [10]
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.
Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...
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.

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).
