乙酸异丁酯制备
1.由异丁醇与乙酐在硫酸存在下酯化而得。将乙酐和异丁醇混合后滴加硫酸，稍冷后加热回流5-6h，回流液用水洗2-3次，用碳酸钠中和，用水洗至中性，用氯化钙干燥，在油浴上减压分馏即得成品。
精制方法：所含杂质除水、乙酸和异丁醇外，尚含有同系物的异松体混合物。精制时用碳酸氢钠或碳酸钠饱和水溶液中和、洗涤，再用氯化钠饱和水溶液充分洗涤，无水硫酸钠或硫酸镁干燥后精馏。
2.制法：
过氧三氟乙酸溶液的制备：于盛有50mL二氯甲烷的反应瓶中，加入90%的H2O28.2mL（0.3mol），冷却下慢慢滴加三氟乙酸酐50.8mL（0.36mol）。加完后充分搅拌备用。于装有搅拌器、滴液漏斗、回流冷凝器的反应瓶中，加入130g干燥、研细的磷酸氢二钠，150mL二氯甲烷合甲基异丁基酮（2）20.0g（0.2mol），搅拌下于20min内滴加上述过氧三氟乙酸溶液，滴加过程中反应放热，剧烈回流。加完后继续加热回流反应30min。冷后，滤去不溶性的盐，并用二氯甲烷洗涤。合并滤液和洗涤液，用10%的碳酸钠溶液洗涤，无水硫酸钠干燥。常压蒸出大部分溶剂后，于装有分馏头的分馏装置中分馏，控制回流比，收集114～115.5℃的馏分，得无色透明液体（1）19.5g，收率84%。
