Abstract
Although feedstocks of L-mannose prepared from hydrocyanation of L-arabinose contain inhibitors to the soluble molybdate-catalyzed epimerization of L-mannose to L-glucose, experimental conditions have been found which minimize such inhibition. A method is presented for improving the yield of L-glucose in a preparative route using hydrocyanation of L-arabinose as the entry to the L-hexoses by incorporating a soluble molybdate-catalyzed empimerrization stage conducted at a pH below 3.0.
