非离子表面活性剂微乳液的制备及其稳定条件

In this paper ,the W/O micromulsion of Tx-100/ n-amyl alcohol /cyclohexane/water was prepared.The pseudo-ternary phase diagrams were constructed.The structure and the structural transformation of the micromulsion were investigated by electric conductivity method as well .The average size and distribution were determined by static light scattering(SLS). It was found that the microemulsion domain became smaller as the Tx-100/ n-amyl alcohol volume ratio increased.It showed that when TritonX-100 and n-amyl alcohol were in the volume ratio of 1:1 and the volume rate of TritonX-100 ：n-amyl alcohol ：cyclohexane was 1：1：2 was best。The change of electric conductivity agrees with the change of phase behavior。The test results show that with the growth of reaction PH ,the particle size will increase and the dispersity will be better ; the reaction temperature can affect the the dispersity and high temperature is good to dispersity, the particle size will increase.
