合成了谷氨酸二烷基酯类表面活性剂,其链长分别为C_8、C_(10)、C_(12)、C_(14)、C_(16)、C_(18)及C_(18)~(Δ9,10),经IR光谱及~1H NMR谱测定证明了产品的结构,界面张力与表面压的测定结果表明该系列表面活性剂具有较高的表面活性效率。
The dialkyl glutamate surfactants were synthesized and their chain lengths were C_8, C_ (10), C_ (12), C_ (14), C_ (16), C_ (18) and C_ (18) ~ (Δ9,10). The structure of the product was confirmed by IR spectrum and ~ 1H NMR spectroscopy. The results of interfacial tension and surface pressure show that the surfactant has higher surface activity efficiency.
