Abstract: In this paper the mechanism of the extraction of mercury acetate by primary amine N1923 is reported. The results show that the extraction mechanism varied with the acidity of water phase. The amine extracts mercury(Ⅰ)acetate by coordination mechanism at high pH value and in the system of conecentrated acetic acid N1923 extracts it by adduct mechanism. The extraction reactions are as follows: The cquilibrium constant and the heat of rcaction(ΔH) have been calculated. And IR, NMR spectra were applied in studying the bonding characteristic of the extracted compounds.
