SEPARATION METHOD OF URACIL FROM URACIL RIBONUCLEOTIDE HYDROLY SATES

摘要

A method for separating uracil from uracil ribonucleosied hydrolysate comprises mixing strong acid hydrolysate of 5'-uridine monophosphate obtd. in the prodn. of nucleic acid seasoning by the fermentation with 18-24 N sulphate soln, hydrolyzing the mixt. at 95-115≦̸C for 1.5-2.5 hr, removing the reacting material of impurities through the multiporous resin tube, and concentrating the effluent.
