Nd, La and Y triphosphates were prepared via the reaction of potassium ionol ethyl phosphate with the corresponding lanthanide nitrates or chlorides in water. According to the X-ray diffraction data, the recrystallised reaction products were dimers. The products did not contain water, were readily soluble in hydrocarbon solvents and demonstrated promising catalytic properties in the polymerisation of butadiene and DL-dilactide.
通过在水溶液中将相应镧系硝酸盐或氯化物与钾离子酚乙基磷酸盐反应,制备了Nd、La和Y三膦酸盐。根据X射线衍射数据,重结晶反应产物为二聚体。产物不含水,易溶于烃类溶剂,并在丁二烯和DL-二乳酸酯聚合中展现出有潜力的催化性能。
