| Ethylenediamine could not only reacted with Y , but also formed the ions [X (en) 2] 2 + with X, that is to say, the X ions were taken by ethylenediamine in the form of [X (en) 2] 2 + complexes from the water core to the interface of the nuclear center to make the X-ion diffuse continuously outward from the center. |

The reactions are carried out in the microemulsion systems. In the microemulsion system, the water core of W/O type (water in oil) was formed, which included X-ions. When Y added to the system, Y didn¡¯t dissolve in dispersed oil phase. The intermediates generated by reaction (2) both contained hydrophilic group and hydrophobic group, and created favorable conditions by played a bridge role in the reactions on oil-water interfacial. In the reaction, ethylenediamine didn¡¯t only reacted with the Y, but also formed [X(en)2]2+ with the X-ions. The X-ions were carried from the centre of water core to interface of water core, which were formed [X (en) 2] 2 + complexes by ethylenediamine. The X-ions continuously diffused outward from the center. Keywords: hydrophily, ethylenediamine, intermediates, system |
