摘要：
A process of preparing a L-ribose fraction having greater than 97% purity starting from an aqueous solution of L-arabinose is provided by utilizing an epimerization reaction conducted in the presence of a Mo compound and eluting the product formed by said epimerization reaction through a separation zone containing a strong acid cation exchange resin. A process of crystallized said L-ribose fraction under conditions effective to form monohydrate L-ribose crystals is also disclosed.
