It was found that tetrakis(hydroxymethyl)glycoluril is unstable in aqueous solutions and undergoes stepwise dehydroxymethylation. The products of this process were identified by HPLC, 1D and 2D NMR spectroscopy. The main product of hydrolytic degradation at room temperature is tris(hydroxymethyl)glycoluril, which may be conditioned by the thermodynamic characteristics of the reaction. Further dehydroxymethylation
发现四(羟甲基)甘脲在水溶液中不稳定并且经历逐步的脱羟甲基化。该过程的产物通过HPLC,1D和2D NMR光谱法鉴定。在室温下水解降解的主要产物是三(羟甲基)甘脲,其可以通过反应的热力学特性来调节。在更严格的条件下发生进一步的脱羟甲基化以产生二和单羟甲基甘脲衍生物。
