METHOD OF PREPARING 3-ACETYL-5,5-DIMETHYLHYDANTION

摘要

FIELD: synthesis of heterocyclic compounds, more particularly low-temperature peroxide bleaching. SUBSTANCE: 3-acetyl-5,5-dimethylhydantion is prepared by reacting 5,5-dimethylhydantion with acetic anhydride at 110-120 C at 5,5-dimethylhydantion to acetic anhydride molar ratio of 1:3 to 1:5. EFFECT: improved properties of pure 3-acetyl-5,5-dimethylhydantion. 1 ex, 3 dwg, 1 tbl
