The products of decomposition of solutions of p-chlorobenzenediazonium tetrafluoroborate in aqueous buffer solutions (pH 9.0–10.3; ionic strength 0.1–0.5) at 20.0° have been analyzed quantitatively. Up to eleven low molecular weight compounds could be identified besides the major product, the complex polymeric diazo tar. The distribution of products is influenced by trace amounts of oxygen as well
定量分析了在20.0°时缓冲水溶液(pH 9.0-10.3;离子强度0.1-0.5)中对氯苯重氮四氟硼酸盐溶液的分解产物。除了主要产物复杂的聚合重氮焦油外,还可以鉴定出多达11种低分子量化合物。产物的分布受痕量氧气以及对氯苯酚和自由基捕获剂碘乙酸的影响。讨论了产物形成的机理。
