LEWATIT® K 2649

Lewatit® K 2649 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.

lt has been dried and can be directly used in applications requiring anhydrous conditions.

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

In reactions involving the use of or formation of water, Lewatit® K 2629 should be used and not Lewatit® K 2649. Lewatit® K 2649 is the dried form of Lewatit® K 2629.

Lewatit® K 2649 is especially suitable for the following applications:
 

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