摘要: 研究磷酸化反应中核黄素与POCl3及H2O的配比、反应温度、反应时间等因素对核黄素磷酸钠合成的影响。结果表明,在吡啶和乙腈的混合溶剂中,使核黄素与其4倍摩尔量的三氯氧磷在35℃左右反应2h,然后水解反应混合物,再用NaOH溶液中和,能够以75%以上的收率得到核黄素磷酸钠。

Abstract: Effects of riboflavin-phosphorus oxychloride-water ratio,phosphorylation reaction time,and reaction temperature on preparation of riboflavin sodium phosphate were investigated. The results showed that reaction product of riboflavin and 4-times moles of phosphorus oxychloride reacting for 2 h at about 35 ℃ in the mixture of pyridine and acetonitrile as a solvent is hydrolyzed and then neutralized with aqueous sodium hydroxide solution,and then more than 75% riboflavin sodium phosphate is obtained.
