Lewatit® K 2640 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 special process has been used to hyper-activate the sulfonic acid groups of the reactive centers, increasing the acidity and reactivity of this catalyst relative to conventional polymer catalysts. Lewatit K 2640 is particularly suitable for the:- Phenol alkylation with olefins
- Olefin oligomerizations
- Etherification and alkylation of larger polar and non-polar molecules
In reactions involving the use of or formation of water, Lewatit K 2620 should be used and not Lewatit 2640, Lewatit K 2640 is the dried form of Lewatit K 2620.Information provided by Lanxess. |
