Abstract

Simple extraction of an aqueous solution of potassium peroxydisulfate and two equivalent of tetrabutylammonium hydrogen sulfate with methylene chloride, drying, filtration, and evaporation gave white crystals of n-tetrabutylammonium peroxydisulfate ((n-Bu 4 N) 2 S 2 O 8 , TBA 2 S 2 O 8 ) which was several times washed with pure water and then dried at 25 °C under vacuum in a desiccator for a couple days.
