英语翻译
Finely ground iodosobenzene diacetate
2
(32.2 g.,0.10 mole) is placed in a 250-ml.beaker,and 150
ml.of 3N sodium hydroxideis added over a 5-minute period with vigorous stirring.The lumps of solid
that form are triturated with a stirring rod or spatula for 15 minutes,and the reaction mixture stands for
an additional 45 minutes to complete the reaction.One hundred milliliters of water is added,the mixture
is stirred vigorously,and the crude,solid iodosobenzeneis collected on a Büchner funnel.The wet solid
is returned to the beaker and triturated in 200 ml.of water.The solidis again collected on the Büchner
funnel,washed there with 200 ml.of water,and dried by maintaining suction.Final purification is
effected by triturating the dried solid in 75 ml.of chloroformin a beaker.The iodosobenzeneis
separated by filtration (Note 1)and air-dried; weight 18.7–20.5 g.(85–93%); m.p.210° (Caution!
Explodes!).Iodometric titration

Answer 1

细磨的醋酸碘苯（这是一个氧化剂和乙酰化剂, 有商品出售）
将化合物 2（32.2克,0.10摩尔）放置于一个250 ml.烧杯,在5分钟以上的时间内在剧烈搅拌下滴加150毫升3N的氢氧化钠溶液.所生成的大块固体花15分钟用搅拌棒或刮刀压碎,然后反应混合物静置45分钟以完成反应.加入100毫升水,并剧烈搅拌. 由布氏漏斗收集固体粗产物醋酸碘苯,该湿固体转移到一个烧杯,加入200ml 水并使其分散, 再由布氏漏斗收集, 用200ml 水洗,保持抽滤来干燥. 最后的纯化是将抽滤干燥的产物在烧杯中用75 ml氯仿来分散.醋酸碘苯是通过过滤来分离（见注1）, 空气干燥；重18.7–20.5克（85–93%）；熔点210°（注意!爆炸!）碘量滴定法测定
