ABSTRACT:
A process for the liquid phase adsorptive separation of arabinose from an aqueous feed mixture of monosaccharides containing arabinose along with other aldoses and ketoses. The feed is contacted with an ammonium X-type zeolite. Arabinose is selectively absorbed to the substantial exclusion of other aldoses and ketoses and thereafter is recovered in high purity by desorption with water. The process can be carried out on a commercial scale by means of a simulated moving bed flow scheme.
