Abstract
|
|
|
|
The solubilization sites of some phenyl alkanols such as phenol, benzyl alcohol, phenethyl alcohol, 3-phenyl-1-propanol solubilized in 0.2 M aqueous sodium dodecylsulfate micelle solution was studied by two dimensional heteronuclear correlation spectroscopy (2D C-H COSY). The results show more quantitative and clear solubilization sites in the SDS micelle than previous results using 1H-NMR spectrum integration. We found that most of the phenyl alkanols penetrate into the core of SDS micelle, and the insertion depth was 6.5∼7.0 methylene units from α-methylene.
