LEWATIT® K 2440

Lewatit® K 2440 is a strongly acidic, macroporous polymer-based catalyst in spherical bead form, containing sulfonic acid groups. It is ideally suited as a heterogeneous catalyst for organic reactions and for the processing of aqueous as well as 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.
