【摘要】 <正>癸基萘磺酸钠(SDNS)是一种广泛应用的阴离子型表面活性剂。我们利用核磁共振已经研究了298K 和313K 重水溶剂中 SDNS 胶束的性能特征,而且对 SDNS 和 Triton X-100 (TX-100)及十二烷基磺酸钠(SDSN)的二元混合溶液近期进行了研究。更多还原

【Abstract】 We have studied the characteristics of sodium 4-decyl naphthalene sulfonate(SDNS)-Triton X-100(TX-100)and sodium dodecyl sulfonate(SDSN)-SDNS mixed solutions,in which SDNS -TX-100 and SDNS-SDSN mixed micelles were formed at the experimental concentrations.In the mixed m icelle of SDNS-TX-100 the phenoxy rings of the TX-100 are embedded in the near vicinity of the alkyl chains of SDNS and the poly-oxy ethylene segments but the first oxy-ethylene group,to which the phenoxy ring is adjacent,of TX-100 molecule are located near the naphthyl rings.So the naphthyi rings of SDNS and the phenoxy rings of TX-100 are more open in the mixed micelles than those in their individual miceiles.And in the mixed miceile of SDNS-SDSN system the SDNS molecules are in single molecular state for the fraction of SDNS is little and these SDNS molecules are distributed in the SDSN media.While the naphthyl ring protruding from the hydrophobic region separates the sulfonate groups of SDSN to weaken the electrostatic repulsion, the mixed micelles can be packed more closely than that in the individual SDSN micelles.更多还原
