叔丁基过氧化氢制备

1.叔丁醇与硫酸反应生成硫酸氢叔丁酯，再与过氧化氢反应而得。将叔丁醇加入反应锅，搅拌下于35℃加入过氧化氢，然后升温至50℃，滴加70%硫酸，加完后反应5h，温度保持在55-60℃，静置分层，取上部油层用无水硫酸钠干燥，过滤，得叔丁基过氧化氢。

2.制法：

于装有搅拌器、温度计、滴液漏斗的反应瓶中，加入叔丁醇（2）74g（1.0mol），冰浴冷却，加入140g70%的硫酸（1.0mol），于5℃反应生成硫酸单叔丁酯。而后0～5℃滴加27%的过氧化氢126g（1.0mol），约30min加完。加完后室温放置过夜。分出有机层，用碳酸镁和10mL水组成的悬浊液中和，20mL水洗涤，无水硫酸镁干燥，得产品70.5g，其中含66%的叔丁基氢过氧化物（1），34%的过氧化二叔丁基，活性氧含量11.74%。用填充柱进行减压分馏，收集12～13℃/2.66kPa的馏分为过氧化二叔丁基，4.5～5℃/266Pa的馏分为化合物（1），绝对不要常压蒸馏。
