Lewatit® K 2640 is a strongly acidic, macroporous, polymer-based resin in spherical bead form, with sulfonic acid groups. lt is ideally suited as a heterogeneous catalyst for organic reactions and for the processing of aqueous and organic liquids.

A special processs has been used to hyper-activate the sulfonic acid groups of the reactive centres, increasing the acidity and reactivity of this catalyst relative to conventional polymer catalysts.

Lewatit® K 2640 is particularly suitable for the:

  • phenol alkylation with olefins
  • olefin oligomerizations
  • etherification and alkylation of larger polar and non-polar molecules

In reactions involving the use of or formation of water, Lewatit® K 2620 should be used and not Lewatit® K 2640. Lewatit® K 2640 is the dried form of Lewatit® K 2620.
