The Interfacial Properties of Primary Amine N1923 in Different Diluents
Abstract:
The interfacial properties of primary amine N1923 in different diluents 0.1 mol/L (H,Na)NO3 (pH=2.34) liquid/liquid systems have been studied.The interfacial parameters, cmin and AI, of N1923 have been obtained.It was suggested that the monomeric N1923 molecule was the active species adsorbed at the interface.The interfacial activity of N1923 in different systems decreased as follows: n-heptane, cyclohexane, benzene, toluene, carbon tetrachloride, chloroform, isoamyl acetate and methyliso-butylketone(MIBK).This results were possibly due to the interaction between diluents and extractant, extractant and water molecules near interfacial layer, and diluents and water molecules near interfacial layer.The relationship between the interfacial properties and extraction reaction have also been discussed.
