Abstract
The invention provides a method for producing soluble neodymium chloride complex using neodymium chloride aqueous solution as raw material, thereby avoiding the use of anhydrous neodymium chloride, simplifying the synthesis process and reducing the cost for synthesizing neodymium chloride complex. The neodymium chloride complex produced by this method is soluble not only in polar solvent, but also in nonpolar solvent. Such neodymium chloride complex also has good dissolvability in aliphatic hydrocarbon solvent which has relatively weaker solution power, and even in aliphatic hydrocarbon solvent with 6 or less carbon atoms which has even lower solution power. Since neodymium chloride complex is soluble in aliphatic hydrocarbon solvent, its transportation may be conducted, which is convenient for industrial application and contributes to improve the utilization efficiency of rare earth.
