改进的直接萃取法制备环烷酸钕杨继华，逄束芬，龚志（中国科学院长春应用化学研究所长春１３００２２）关键词环烷酸钕，直接萃取法，氢氧化钠环烷酸钕是制备稀土合成橡胶常用的催化剂组分之一，可采用固体法、间接萃取法和目前一般采用ＮＨ４ＯＨ作用下的直接萃取法制备...
An improved direct extraction method for preparation of neodymium naphthenate with NaOH instead of NH_4OH was proposed. In comparison with original method, the improved method has many advantages such as fast reaction rate' easy monitoring and operation as well as absence of irritative smell. The product obtained therewith can be used for formulation of diene stereospecific polymerization catalyst with good catalytic property.
