Impurities in surfactants. Surfactant mixtures made from the ethoxylation of fatty amines can be contaminated by impurities such as 1,4-dioxane and ethylene oxide. The most frequent impurities are polyethylene glycols, which are formed when ethylene oxides polymerize instead of reacting with a fatty amine. 43 …
In the ethylene dichloride route, the initial product of this reaction is ethylenediamine. In the presence of excess ethylene dichloride, the initial ethyleneamine is extended by one ethylene unit. The terminal alkyl chloride reacts with ammonia to give the amine, and the polyamine chain can be … See more Ethyleneamines are a class of amine compounds containing ethylene (-CH2CH2-) linkages between amine groups. These compounds are generally colorless, low-viscosity liquids with a fishy amine odor.
