一般說明

过硫酸钠,又称过氧二硫酸钠,是一种无机化合物,是一种水溶性强氧化剂,稳定性好,易于处理。它通常用作有机合成反应的氧化剂,如过渡金属催化反应或无金属反应。此外,它还被用作聚合引发剂和通过热活化分解合成硫酸盐自由基阴离子。

應用

过硫酸钠可用作氧化剂:
  • 2-炔基苯并腈与芳基亚磺酸钠的自由基环化级联反应,以合成磺化茚酮。
  • 通过二氧化硅负载的氯化铝催化 Baeyer-Villiger 氧化将环和无环酮转化为内酯或酯。
还可用作苯乙烯聚合的引发剂,以合成聚苯乙烯。

Contaminant destruction with in situ chemical oxidation (ISCO) using persulfate (peroxydisulfate, S2O8(2-)) can be enhanced by activation, which increases the rate of persulfate decomposition to sulfate radicals (SO4*-). This step initiates a chain of radical reactions involving species (including SO4*-
