PROCESS FOR CRYSTALISATION OF SODIUM 5-GUALYNATE |
| 摘要 |
5'-guanylic acid disodium (GMP2Na). 7H2O is crystallized by using a Na-phosphate salt and a hydrophillic organic solvent. Thus, a soln. of 5g Na2H2PO4 in 500ml of 25% GMP2Na soln. is adjusted with NaOH to pH8.2 and mixed with 500ml MeOH(99%) and a small amt. of GMP2Na.7H2O as crystall nucleus to give 162 g columnar crystal of GMP2Na.7H2O.
