引言中性磷酸酯一般是指磷酸中的三个羟基被酯化或被烷基取代的化合物,有(RO)_3P=O、(RO)_2P=O、ROP=O、R_3P=O 四种类型。中性磷酸酯作为稀土元素的萃取剂,近年来文献已有报导。但用稀土中性磷酸酯络合物作为异戊二烯聚合的催化剂,除了用 P～350作催化剂有报导以外,用其他类型中性磷酸酯作催化剂,文献尚未见报导。本文研究了不同类型的中性磷酸酯氯化稀土络合物和三异丁基铝组成
Introduction Neutral phosphate generally refers to compounds in which the three hydroxyl groups in the phosphoric acid are esterified or alkyl-substituted. There are four types of (RO) _3P = O, (RO) _2P = O, ROP = O and R_3P = O . Neutral phosphate as a rare earth extraction agent, literature has been reported in recent years. However, rare earth neutral phosphate complexes as isoprene polymerization catalyst, in addition to P ~ 350 as a catalyst has been reported, with other types of neutral phosphate as a catalyst, the literature has not been reported. In this paper, the different types of neutral phosphate ester rare earth chloride complexes and triisobutyl aluminum composition
