摘　　要：通过静电力自组装制得了树枝状聚(胺-酯)-月桂酸(PAE(NH2)8-LA),并利用FTIR技术对PAE(NH2)8-LA进行了表征;考察了月桂酸含量、PAE(NH2)8浓度及水相pH对染料相转移率的影响。实验结果表明,染料的相转移率随月桂酸含量和水相pH的增大呈先增大后减小的趋势,随PAE(NH2)8浓度的增大而增大。在20 mL质量分数为9.09%的月桂酸甲苯溶液、10 mL浓度为4.2×10-4mol/L的PAE(NH2)8水溶液与10 mL浓度约为1.200×10-5mol/L的染料水溶液的混合液中,当水相pH分别为7.72,6.64,7.72时,染料达旦黄、甲基橙、二甲酚橙的相转移率分别达到最大值(49.60%,41.35%,35.58%)。Dendritic poly （amine-ester） （PAE （NH2） 8） -lauric acid was prepared by electrostatic force self-assembling and was characterized by means of FTIR. The effects of lauric acid dosage, PAE （NH2） 8 mole concentration and aqueous phase pH on the phase-transfer rates of dyes（namely methyl orange, titan yellow and xylenol orange）were investigated. The results showed that the phase-transfer rates of the dyes increased firstly and then decreased with increasing lauric acid dosage and aqueous phase pH, and increased with increasing PAE （NH2）8 dosage. In the mixture of 20 mL lauric acid toluene solution with 9.09% （w） lauric acid, 10 mL PAE （NH2） 8 aqueous solution with 4.2 x×10^-4 mol/L PAE （NH2） 8 and 10 mL dye （methyl orange, titan yellow or xylenol orange） aqueous solution with about 1.200 ×10^-5 mol/L dye, when aqueous phase pH were 7.72, 6.64 and 7.72, the phasetransfer rates of titan yellow, methyl orange and xylenol orange reached the maximum value of 40.06%, 47.09% and 33.70%, respectively.
