LEWATIT® S 4468

Product Description

Lewatit® S 4468 is a food grade, macroporous, monodisperse, medium basic anion exchange resin (tertiary and quaternary amino groups) based on a styrene-divinylbenzene copolymer.

In its form of a free base, the Lewatit® S 4468 is suitable for the removal of acid and simultaneous decolorisation of solutions of organic products such as glucose, fructose or dextrose (particulary suitable due to low fructose formation) and other sugars, etc.

The macroporous structure and the balanced relation between weakly and strongly basic groups ensures very good adsorption of organic substances (e.g. colorants) and of organic acids and mineral acids. The substances adsorbed can easily be desorbed by regeneration with caustic soda solution.

If using Lewatit® S 4468 to treat potable water and the aqueous solutions listed above, special care should be given to the initial cycles of the new resin. Please refer to the recommended start-up conditions available on request.
