从最活跃到最稳定的过氧化物可以通过三种方法的连贯组来定量确定。方法一（回流nal -异丙醇）推荐用于易还原的过氧化物。方法二（回流nal -乙酸-6% h2o）主要是测定二芳烷基过氧化物，如过氧化二氨基的方法。方法三（回流法）将确定最稳定的异烷基过氧化物，并定量还原许多非过氧化物。讨论了若干临时程序。强调了过量碘化物的重要性和水含量在还原力调节中的关键作用。这些方法的范围通过它们在测定许多纯化合物中的应用得到证明。方法1的相对标准偏差为0.23%，方法2为0.30%，方法3为0.32%。
Peroxides from the most active to the most stable can be quantitatively determined by means of a coherent group of three methods. Method I (refluxing Nal-isopropyl alcohol) is recommended for alleasily reduced peroxides. Method II (refluxing Nal-acetic acid-6% H20) is primarily an assay procedure for diaralkyl peroxides, such as dicumyl peroxide. Method III (refluxing Nal-acetic acid-HCI) will determine the most stable di-ferf-alkyl peroxides and quanti-tatively reduce many nonperoxidic compounds. Several interim pro-cedures are discussed. The impor-tance of excess iodide and the key role of H20 content in the regulation of reducing power are stressed. The scope of the methods is demonstrated by their application to the determina-tion of many pure compounds. Rela-tive standard deviations were 0.23% for Method I, 0.30% for Method II, and 0.32% for Method III.
