含有双胺基的三硅氧烷中的伯胺基与D-葡萄糖酸-δ-内酯进行酰胺化,仲胺基与低聚乙二醇甲醚缩水甘油醚、二缩水甘油醚进行烷基化,制备了新型含硅表面活性剂Me3SiOSiMeR1OSiMe3 [R1=(CH2)3NR2(CH2)2NHCO(CHOH)4CH2OH; R2=H, CH2CH(OH)CH2O(CH2CH2O)xCH3, x=1, 2, 3] (1a, 2a~2c)和(CH2OCH2)y(Me3SiOSiMeR3OSiMe3)2 [R3=(CH2)3NR4~(CH2)2NHCO(CHOH)4CH2OH; R4=CH2CH(OH)CH2OCH2, y=0, 1, 2] (3a~3c).这些化合物的结构用1H, 13C核磁共振仪和元素分析仪进行鉴定.研究了这些新型含硅表面活性剂的界面性能,在浓度分别为10-4和10-5 mol·L-1时可以将水的表面张力降低至约21 mN·m-1.

A new family of glucosamide-based trisiloxanes of the general formula Me3SiOSiMeR1OSiMe3[R1=(CH2)3NR2(CH2)2NHCO(CHOH)4CH2OH; R2=H, CH2CH(OH)CH2O(CH2CH2O)xCH3, x=1, 2, 3 [ST5HZ](1a, 2a~2c)] and (CH2OCH2)y(Me3SiOSiMeR3OSiMe3)2[R3=(CH2)3NR4(CH2)2NHCO(CHOH)4CH2OH; R4=CH2CH(OH)CH2OCH2, y=0, 1, 2] (3a~3c) have been prepared and characterized. They were prepared by the amidation of the amine functional trisiloxane with the D-gluconic acid δ-lactone and then by the alkylation of the secondary amine with the oligoethylene glycol methyl glycidyl ethers or the oligoethylene glycol diglycidyl ethers. They were structurally characterized by proton, 13C NMR and elemental analysis. The interfacial properties of this family of glucosamide-based trisiloxanes were studied. Members of this family reduced the surface tension of water to approximately 21 mN·m-1 at concentration levels of 10-4 and 10-5 mol·L-1.
