Process for the preparation of high purity iridium (III) chloride hydrate

摘要

As a process for producing high purity iridium (III) chloride hydrate, (1) solid H ₂ comprising the steps of: providing at least one material selected from the [IrCl _6] hydrate, 1 wt% or more H ₂ [IrCl _6] aqueous solution, and solid _tetrahydrate IrCl group consisting of; (2) The molar ratio of monohydroxy compound miscible with water in any ratio, primary monoalcohol containing 4 to 6 carbon atoms, and Ir (IV): monohydroxy compound is 1: 0.6 to 1000 One or more monohydroxy compounds selected from the group consisting of secondary monoalcohols containing from 4 to 6 carbon atoms are added to the one or more materials provided in step (1) and are 0.2 to 48 in a temperature range of 20 to 120 ° C. Allowing to react for a time and then removing the volatile components from the reaction mixture formed therefrom.
