Sulphonation of Polystyrene Beads.
Strašák, Tomáš
2016 - Czech
This report describes sulphonation of polystyrene beads with narrow size distribution of particles typically with diameter 2-8 µm. These particles serve as starting material for preparation of stationary phase for ion exchange chromatography (IEC). An advantage of this procedure is replace of risk procedures which worked with chlorosulphonic acid or oleum as a sulfonating agent by procedure using concentrated sulphuric acid. Tato výzkumná zpráva popisuje sulfonaci polystyrenových (PS) kuliček s úzkou distribucí velikostí typicky o průměru 2-8 µm. Tyto částice jsou využívány jako stacionární fáze pro iontově výměnnou chromatografii (IEC). Výhodou předkládaného postupu je nahrazení rizikových postupů využívajících při této modifikaci olea nebo kyselinu chlorsírovou jako sulfonačního činidla postupem, který používá koncentrovanou kyselinou sírovou.
