The sonolysis of uracil (1) has been studied at 630 kHz in the presence of air, oxygen, nitrogen, and argon. The degradation products were identified by gc-ms analysis. Under aerated conditions the following products were found: uracil glycols (7), isobarbituric acid (8), N-formyl-N'-glyoxylurea (6), 5-hydroxyhydantoin (9), dialuric acid (10), alloxan monohydrate (12), parabanic acid (13), and oxaluric acid (14). In deaerated solutions 6, ...
