Abstract
Quaternary ammonium thiomolybdates are prepared in a two-phase reaction system by contacting an aqueous solution of a thiomolybdate salt with a solution of a quaternary ammonium salt in a water-immiscible organic solvent. For example, mixing a solution of dicocodimethylammonium chloride in toluene with an aqueous solution of potassium thiomolybdate results in a toluene solution containing dicocodimethylammonium thiomolybdate.
