Potassium carbonate-silica: a highly effective stationary phase for the chromatographic removal of organotin impurities.
Organotin impurities in product mixtures can be reduced from stoichiometric levels to approximately 15 parts per million by column chromatography using 10% w/w anhydrous potassium carbonate-silica as a stationary phase.
