【摘要】 用^３１Ｐ核磁共振波谱定性定量分析了烷基磷酸酯盐（Ｉ）和烷基聚氧乙烯醚磷酸酯盐（Ⅱ）中各含磷组分及其含量。研究了溶液ｐＨ值、氯化钠含量、样品浓度等对各组分^３１Ｐ化学位移的影响。探讨了影响定量准确度的因素；找出了最佳分析条件。更多还原

【Abstract】 Phosphorus-containing components of dodecyl phosphate(I) and dodecyl polyethylene glycol phosphate(Ⅱ)were identified and determined by 31P-NMR spectra. The effects of pH,NaCl content,and concentration of sample solution on 31P chemical shifts of each band have been investigated.更多还原
