Lewatit® K 2420 is a strongly acidic, medium crosslinked, macroporous, polymer-based catalyst in spherical bead form, with sulfonic acid groups.
It is ideally suited as a heterogeneous catalyst for organic reactions and for the processing of aqueous and organic liquids at temperatures up to 150°C.
A special process has been used to hyper-activate the sulfonic acid groups of the reactive centres, increasing the acidity and reactivity of this catalyst relative to conventionally sulfonated polymer catalysts.
