Abstract: An adsorbent comprising a crystalline aluminosilicate suitable for use in a process for separating a component from a feed mixture comprising an aqueous solution of a mixture of different components, such as a mixture of saccharides, by contacting the mixture with the adsorbent. The adsorbent selectively adsorbs a component from the feed mixture. The undesirable tendency for the silicon constituent of the crystalline aluminosilicate to dissolve in the aqueous system is minimized by the impregnation of the crystalline aluminosilicate with aluminum cations.

Abstract: A process for separating a component from a feed mixture comprising an aqueous solution of a mixture of different components, such as a mixture of saccharides, in which the mixture is contacted with an adsorbent comprising a crystalline aluminosilicate which selectively adsorbs a component from the feed mixture. The adsorbed component is then recovered by contacting the adsorbent with a desorbent material such as water to effect the desorption of the adsorbed component from the adsorbent. There is an undesirable tendency for the silicon constituent of the crystalline aluminosilicate to dissolve in the aqueous system. The process comprises the impregnation of the crystalline aluminosilicate with aluminum cations which substantially reduces the undesirable dissolution.
