Neodymium trichloride solubility

Intercomparison op Reported Solubilities for Neodymium Trichloride in Methanol and in Ethanol0 (at 25°C)... 

Lanthanum and neodymium trichlorides are readily soluble in ethylene glycol and in glycerol [Table XXVI (228,288)]. 

The most studied solvent here is pyridine (Table XXIX (178, 298). The reported solubilities parallel the affinities suggested by known solvates—e.g., YCl3-3py, SmCl3-3py, but PrCl3-2py (cf. Section III,C,2). Qualitative information on related solvents is that neodymium trichloride is very sparingly soluble in aniline, but insoluble in toluidine, pyrrole, piperidine, and quinoline. Praseodymium trichloride is also insoluble in quinoline, but yttrium trichloride is slightly soluble in this solvent (178). 

The temperature dependences of solubilities of the trichlorides of lanthanum, praseodymium, and neodymium in aqueous ammonium chloride solutions (212) are so irregular that no estimate of solution enthalpies can be made from them by the van t Hoff method.
