本文测定了三元体系NH4Cl-SbCl3-HOAc在25℃时平衡态和介稳态的溶度及部分饱和溶液的折光指数, 并绘制了相应的溶度图. 体系在稳定平衡态时有五种固相: NH4Cl、SbCl3(原始盐), 5NH4Cl-SbCl3(1)、2NH4Cl-SbCl3.5HOAc(2)和5NH4Cl-3SbCl3.2.5HOAc(3)(复盐). 一支介稳溶度曲线所对应的固相是3NH4Cl.SbCl3(4). 本文初步描述了以上四种复盐的一些物理化学性质. 体系中合成的二元复盐1和溶剂合复盐2与3文献中均未见报道. 本文提供了一种制备3NH4Cl.SbCl3的新方法.

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.
