Lewatit® S 2328 is a food grade macroporous, strongly acidic cation exchange resin based on a styrene-divinylbenzene copolymer. It is bead-shaped and has a special bead size distribution for a use in the processes mentioned below:- Lewatit WS system (fluidized bed)
- Lewatit VWS system (compound fluidized bed)
- Standard co current regenerated system
Lewatit S 2328 contains sulfonic acid groups and is therefore highly suitable for heterogeneous proton catalysis of organic reactions. Optimum crosslinking, its porous structure and the large inner surface area of the polymer give larger molecules good access to the active center of the resin beads. In the hydrogen from Lewatit S 2328 is therefore particularly suitable for:- the inversion of sugar solutions, e.g. in the production of fructose glucose
- the decationization as part of the inversion of sugar solutions
- the decolorization of sugar solutions containing hydrophilic high-molecular cationic organic substances, e.g. molasses and amino acid solutions
If using Lewatit S 2328 to treat potable water and the aqueous solutions listed above, special care should be given to the initial cycles of the new resin.Information provided by Lanxess. |
