    摘要: An improved process for preparing riboflavin 5'-phosphate (FMN) or its monosodium salt by reacting riboflavin with excess phosphorus oxychloride in a solvent, hydrolyzing of the resulting reaction mixture and, if desired, partially neutralizing with aqueous sodium hydroxide solution, comprises reacting the riboflavin with from 1.2 to 3 moles of phosphorus oxychloride per mole of riboflavin in a suitable lactone, especially .gamma.-butyrolactone, as solvent. The process is particularly advantageous when the reaction mixture is hydrolyzed at from 80.degree. to 90.degree. C. continuously or batchwise.

    摘要: A process for the purification of riboflavine-5'-monophosphate comprising subjecting crude riboflavine-5'-monophosphate to chromatography using a column packed with a weakly basic anion-exchange resin having a skeleton of a crosslinked polyacrylic acid ester or polymethacrylic acid ester in which at least a part of the ester linkages thereof are converted into amide linkages represented by the following formula (1): ##STR1## to obtain a fraction of riboflavine-5'-monophosphate containing a reduced amount of impurities from an eluate of the column is disclosed.
