用半微量相平衡法研究了Zn(NO_3)_2-His/Met/Phe-H_2O在25℃及全浓度范围内的溶度性质,构置了体系的溶度图及饱和溶液的折光指数-组成图,发现并制备了未见文献报道的固液同组成三元化合物Zn(His)(NO_3)_2·(1/2)H_2O与Zn(Met)(NO_3)_2·(1/2)H_2O和固液异组成三元化合物Zn(Met)_3(NO_3)_2·H_2O,Zn(Phe)(NO_3)_2·H_2O与Zn(Phe)_3(NO_3)_2·H_2O.通过化学分析、元素分析、IR光谱、X射线粉末衍射、TG-DTG等对其组成、结构及热稳定性进行了研究.
The solubility properties of Zn (NO_3) _2-His / Met / Phe-H_2O at 25 ℃ and the full range of concentration were studied by semi-micro phase equilibrium method. The solubility diagrams of the system and the refractive index of the saturated solution The results showed that the solid-liquid ternary compounds Zn (His) (NO_3) _2 · (1/2) H_2O and Zn (Met) (NO_3) _2 · (1/2) H_2O The solid-liquid heterostructures consist of ternary compounds Zn (Met) _3 (NO_3) _2 · H_2O, Zn (Phe) (NO_3) _2 · H_2O and Zn (Phe) _3 (NO_3) _2 · H_2O. Spectroscopy, X-ray powder diffraction, TG-DTG such as its composition, structure and thermal stability were studied.
