A study on ternary system of NH4Cl-SbCl3-HOAc(25℃)

Abstract

Solubilities and refractive indexes of saturated solns. were determine for the title system at 25?and the phase diagram was constructed. There are 5 equilibrium solid phases (NH4Cl, SbCl3, 5NH4Cl.SbCl3, 2NH4Cl.SbCl3.1.5HOAc, and 5NH4Cl.3SbCl3.2.5HOAc). The latter are new. A metastable 3NH4Cl.SbCl3 phase was found and its solubilities were determine Some physicochem. properties were determine for the complex compounds The x-ray diffraction results show that 5NH4Cl.SbCl3 decomps. slowly with the formation of 3NH4Cl.SbCl3. A new method for preparing 3NH4Cl.SbCl3 is described.
