Abstract

A flow scheme is presented for the production of high purity D-allose from D-glucose. The key reaction is epimerization of D-glucose at C-3 to afford D-allose in per pass yields of at least 7%. The epimerization reaction product is then subjected to concentration, decolorization, and deionization before entering a separation zone, preferably a sorptive separation zone, from which an extract stream enriched in D-allose is obtained.
