Synthesis，characterization and foaming ability of glucose type anionic surfactant

摘要:

以葡萄糖、十二胺和乙醛酸为原料制备了一种葡萄糖型阴离子表面活性剂，采用吊片法、临界胶束浓度法和改进的Ross-Miles法对产物的表面张力、HLB值和起泡性进行了测试，并以傅立叶红外光谱、核磁共振氢谱、元素分析表征了产物的结构。结果表明，合成的葡萄糖型阴离子表面活性剂的表面张力为39.82mN/m，其临界胶束浓度为0.031mmol/L，HLB值为16.46；同时合成的葡萄糖型阴离子表面活性剂具有良好的起泡性和稳泡性。

Abstract:

The glucose type anionic surfactant is synthesized by D-glucose, dodecylamine and glyoxylic acid as raw materials. The chemical structures of the product was characterized by means of FTIR ,1HNMR and elemental analysis. The surface tension, HLB value and foaming properties of the product were respectively measured by ring method, CMC method and improved Ross-Miles method. The results showed that the surface tension of glucose type anionic surfactant was 39.82mN/m，the micelle concentration was 0.031mmol/L and the HLB value was 16.46. It was also shown that the glucose type anionic surfactant had excellent foaming ability and foam stability.
