The solution concerns a preparation of highly pure D-ribose. The 15 to 20 percent water solution of D-arabinose is introduced in contact with ion exchange resin with functional quaternary benzyltrimethylammonium groups, with bound molybdenum ions at a temperature of 90 to 100 degrees C for a period of 4 to 6 hours. The reaction mixture of D-ribose, D-arabinose, D-lyxose, D-xylose is used for preparation of crystalline N-phenyl-D-ribosylamine by means of aromatic amine, from whose hydrolysis by water vapour D-ribose is released. After obtaining D-ribose the mixture of sugars in mother liquor can be chromatographically selectively separated on a column with ion exchange resin with functional sulfo groups, which was modified by univalent, bivalent or trivalent metal using from 40 to 60 percent of water solution of ethanol.
