补充资料:碘苯
分子式:C6H5I
分子量:204.01
CAS号:591-50-4
性质:无色液体。熔点-31.27℃,沸点188.3℃,63-64℃(1.07kPa),相对密度1.8308(20/4℃),折光率1.6200(18.5℃),闪点74℃。易溶于乙醚,溶于乙醇和氯仿,不溶于水。见光颜色变黄,有特殊气味。
制备方法:由苯胺经重氮化、置换而得。将30%盐酸、苯胺加入水中,搅拌冷却至2℃,缓缓滴加亚硝酸钠溶液,控制温度不超过12℃。滴加最后一部分亚硝酸钠溶液时,用碘化钾淀粉试纸测试,呈蓝色为反应终点,得重氮化液。将碘化钾溶液分多次加入重氮化液中,此时放出氮气,放置2h,至无氮气逸出为止。冷却后,分去上层水溶液。加10%氢氧化钠溶液使反应液至pH14。进行水蒸气蒸馏,馏出液分去水层,干燥后常压分馏,收集184-188℃馏分,即为碘苯,收率77%。
用途:用于有机合成或用作折光率标准液。
