| titleOfInvention | A kind of production technology of disodium 5'-uridylate |
| abstract | The application relates to the field of nucleotide preparation, and specifically discloses a production process of disodium 5'-uridylate. The production process of disodium 5'-uridylic acid comprises the following steps: after adding 5'-cytidylic acid to water for stirring, then adding sodium nitrite, stirring and mixing; Carry out the reaction, detect by HPLC, and track the reaction process; after the reaction is completed, add an alkaline solution, adjust the pH of the reaction solution to neutrality to obtain a mixed solution; dilute the mixed solution with water and then perform nanofiltration for several times to obtain a nanofiltrate; add organic In the solvent, repeated filtration and crystallization are carried out, and the obtained filter cake is rinsed with an organic solvent to obtain a wet product; the wet product is heated and dried to obtain disodium 5'-uridylate. The production process of the present application adopts nanofiltration means to remove impurities and purify the obtained disodium 5'-uridylate with high yield and high purity. |
