不同状态HDEHP和DMHPA的FTIR光谱研究

STUDY ON FTIR SPECTRA OF HDEHP AND DMHPA IN DIFFERENT STATES

研究了纯二（２－乙基己基）磷酸（ＨＤＥＨＰ）和二（１－甲基庚基）磷酸（ＤＭＨＰＡ）、微乳状液，固体钠盐及萃取稀土有机相的ＦＴＩＲ光谱，了解到萃取剂的微观结构由于烷基Ｒ的排列方式状态及其存在的不同而有差异。

FTIR spectra of pure di(2 ethylhexyl) phosphoric acid (HDEHP),di(1 methylheptyl) phosphoric acid (DMHPA) and their sodium salts,microemulsions,extracted organic phases containing rare earth were studied.It was seen that the microstructures of the two extractants changed with their different alkyl structures and aggregation states.
