LEWATIT® K 2620

Lewatit® K 2620 is a stronlgy acidic, macroporous, polymer-based catalyst in spherical bead from, with sulfonic acid groups. It is ideally suited as a heterogeneous catalyst for organic reactions and for the processing of aqueous and organic liquids.

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 conventional polymer catalyst.

The large pore structure faciliates the trasport of reactants to the reactive centers. A high degree of crosslinking, coupled with a compact bead structure result in high chemical and mechanical stability, enabling the Lewatit® K 2620 to be used in polar and non-polar media.

Therefore, it is especially suitable for use in the following applications :

• Production of the gasoline additives MTBE, ETBE and TAME

• Phenol alkylations, hydration of olefins, esterification, etherification, condensation and alkylation of larger polar and non-polar molecules
