LEWATIT® K 2621

Lewatit® K 2621 is a strongly acidic, macroporous, polymer-based resin in spherical bead form, with sulfonic acid groups. It is ideally suited as a heterogeneous catalyst for organic reactions.

A large pore structure, high degree of crosslinking and good mechanical stability enable this catalyst to be used in polar and non-polar media.

Lewatit® K 2621 is particularly suitable for the:

• production of the gasoline additives MTBE, ETBE and TAME
• phenol alkylation with olefins
• hydration of olefins
• esterification, etherification, condensation and alkylation of larger polar and non-polar molecules
