| 中文摘要: |
| 研究铈量法测定过氧化苯甲酸叔丁酯（TBPB）中叔丁基过氧化氢（TBHP）含量。通过探讨硫酸铈铵标准溶液加入强酸种类、标准溶液酸度和反应温度对TBPB中TBHP含量的影响，确定铈量法准确测定TBPB中TBHP含量的适宜条件为：硫酸铈铵标准溶液中加入硫酸，且配制硫酸溶液时100 mL超纯水中加入了3 mL浓硫酸，测试全程在盛有冰水混合物（0 ℃）的大烧杯中进行。 |
| 英文摘要: |
| Study on the determination of tert butyl hydroperoxide（TBHP）content in tert butyl peroxybenzoate （TBPB） by cerium content method.By exploring the effects of types of adding strong acid to cerium ammonium sulfate standard solution，standard solution acidity and reaction temperature on the TBHP content in TBPB，the suitable conditions for accurately determining the TBHP content in TBPB using the cerium content method were as follows：sulfuric acid was added to the standard solution of cerium ammonium sulfate，3 mL of concentrated sulfuric acid was added to 100 mL of ultrapure water when preparing the sulfuric acid solution，and the entire test was conducted in a large beaker containing a mixture of ice and water（0 ℃）. |
