Zx. Tang et al., A STUDY ON THE TERNARY-SYSTEM SM(NO3)(3)- ACAP-H2O AT 30-DEGREES-C AND THE PREPARATION AND CHARACTERIZATIONS OF THE SM(ACAP)(2)(NO3)(3), Huaxue xuebao, 53(3), 1995, pp. 219-222
The solubilities and the refractive indexes of saturated solutions of
the titled system at 30 degrees C have been studied and the correspoun
ding equilibrium diagram and refractive index diagram were constructed
. Both solubility curve and refractive index curve of the system consi
st of three branches, correspounding to ACAP, Sm(ACAP)(2)(NO3)(3) and
Sm(NO3)(3) . 6H(2)O respectively. The Sm(ACAP)(2)(NO3)(3) is a new com
pound. It was characterized by chemical and elemental analysis, IR spe
ctra, TG-DTG and molar conductivity (in DMF). The influences of the an
ion on the interaction between the ACAP and the rare earth ion has bee
n discussed briefly.
