Abstract

The results of development of physicochemical fundamentals for the synthesis and deep purification of tin tetrachloride have been described. The samples of SnCl₄ have been prepared from elements in a specially designed quartz installation. Prepared SnCl₄ has been purified by rectification on a perforated-plate column. It has been revealed by mass spectrometry that the content of lead admixture after SnCl₄ rectification decreases from 120 to 2 ppm, and the content of admixtures of other metals decreases considerably. Separation factors in liquid–vapor system for hardly separable admixtures have been calculated. The purity of SnCl₄ samples has been confirmed by IR and Raman spectroscopy. The prepared SnCl₄ samples contained 10^–4 wt % of admixtures.

四氯化锡的合成及深度纯化

摘要

已经描述了四氯化锡合成和深度纯化的物理化学基础的发展结果。SnCl ₄样品是由特殊设计的石英装置中的元素制备的。制备的 SnCl ₄已通过在多孔板柱上精馏进行纯化。质谱表明，SnCl ₄精馏后铅掺合料的含量从120ppm降低到2ppm，其他金属掺合料的含量明显降低。已经计算了难以分离的混合物在液-气系统中的分离因子。SnCl ₄样品的纯度已通过红外光谱和拉曼光谱证实。制备的 SnCl ₄样品含有^10–4 wt% 的外加剂。
