ROOM-TEMPERATURE SULFUR CHLORIDE IONIC LIQUIDS IN PROCESSES FOR THE ISOLATION OF NOBLE AND OTHER METALS

摘要

A correlation of interatomic distances (d/A), chalcogen-chlorine bond stretching frequencies (v/cm~(-1)) and ~(35)ClNQR frequencies (MHz) has been performed for crystals of chalcogen chloride complexes of gold(Ⅲ) and osmium(Ⅳ). A conclusion has been drawn as to the functional peculiarities of chalcogen chloride molecules being part of complexes. The state of the complexes under investigation in nonaqueous polar solvents has been studied using Raman spectroscopic and conductometric methods; the form of the species formed in solutions has been established. New ionic liquids - reagents for the comprehensive processing of raw materials containing noble metals - are proposed.
