Abstract—
Extrapure-grade (99.9985 wt % pure) SnCl2 has been prepared from commercially pure metallic tin and hydrogen chloride gas. Purifying the synthesized tin(II) chloride in a fractional distillation column under normal conditions, we obtained extrapure-grade SnCl2 containing under 1 ppm impurities. The samples thus prepared were characterized by inductively coupled plasma mass spectrometry, IR and Raman spectroscopies, and X-ray diffraction.
