The states of water in water/Triton X-100/n-butanol/cyclohexane reverse microemulsion, trapped water, bound water and free water, have been studied at various molar ratio of water to Triton X-100, mass ratio of water to oil (f) and the content of n-butanol by means of Fourier transform infrared spectroscopy (FT-IR). It was found that the water pools formed after Rw being larger than 8 as f was 2.8 and mn-butanol/mTriton X-100 was 0.5|and the number of free water, the trapped water of per Triton X-100 molecule increased with Rw, while the number of the bounded water was almost constant at 2|the mass ratio of water to oil (1~6.7) had little effect on the FT-IR spectroscopy of the reverse microemulsion at Rw of 20 and mn-butanol/mTriton X-100 of 0.5. In addition, the n-butanol molecules interacted with both molecules of Triton X-100 and water, and it retarded the formation of free water.

Key words: reverse microemulsion, FT-IR, water state, Triton X-100, n-butanol
