Continuous epimerization of sugars, in particular D-arabinose to D-ribose |
| abstract |
Pentoses and hexoses are continuously epimerized by heating a sugar in solution in a solvent in the presence of a basic anion exchanger charged with a molybedenum(VI) compound by preparing a D- or L-sugar having cis-disposed OH groups in the 2- and 3-positions of the sugar by continuously passing a homogeneous solution of the corresponding sugar having transdisposed OH groups in the 2- and 3-positions of the sugar in a mixture of water and methanol or ethanol at from 70 DEG to 100 DEG C., preferably at from 73 DEG and 80 DEG C., through a reaction tube which contains the basic anion exchanger charged with the molybdenum(VI) compound, this method being suitable in particular for epimerizing D-arabinose to prepare D-ribose required for the production of riboflavin. |
