Lewatit® K 2649 is a strongly acidic, macroporous, polymer-based resin in spherical bead form, with sulfonic acid groups. It is ideal suited as a heterogeneous catalyst for organic reactions. It has been dried and can be directly used in applications requiring anhydrous conditions. A large pre 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 2649, Lewatit K 2649 is the dried form of Lewatit K 2629. Lewatit K 2649 is particularly suitable for the following applications:- Phenol alkylation with olefins
- Olefin oligomerizations
- Esterification, etherification and alkylation of larger polar and non-polar molecules
