摘　　要：The phase transition and microenvironment properties of the vesicles from tri-ethanolamine dilaurate（2RNC2） in the diluted solution of chloride acid have been studied by meansof DSC and fluorescence method. It is shown that the micropolarity of the vesicles increased withthe decrease of the pH value of the solution, but the phase transition temperature, microviscosityof the vesicles approached the maximum values within pH 23 range. The foaming ability of thesolution also reached the best effect within the same pH range.The phase transition and microenvironment properties of the vesicles from tri-ethanolamine dilaurate(2RNC_2) in the diluted solution of chloride acid have been studied by meansof DSC and fluorescence method. It is shown that the micropolarity of the vesicles increased withthe decrease of the pH value of the solution, but the phase transition temperature, microviscosityof the vesicles approached the maximum values within pH 2~3 range. The foaming ability of thesolution also reached the best effect within the same pH range.
