Lewatit® K 2629 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 and for the processing of aqueous and organic liquids. A large pore structure, high degree of crosslinking and good mechanical stability enable this catalyst to be used in polar and non-polar media. It is very compact and thus of exceptional mechanical stability. Therefore, it is especially suitable for use in the following applications:- Production of the gasoline additives MTBE, ETBE and TAME
- Phenol alkylations and transalkylations, hydration of olefins, esterification, etherification, condensation and alkylation of larger polar and non-polar molecules
- Cation removal, base adsorption from aqueous and organic liquids.
