补充资料：丙基溴

分子式：C3H7Br
分子量：123.00
CAS号：106-94-5

性质：无色易燃液体。熔点-110℃，沸点71℃，相对密度1.3537(20/4℃)，折光率1.4343，折射率1.434，闪点25℃。能与醇、醚混溶，微溶于水。

制备方法：（1）由正丙醇与氢溴酸反应而得。将氢溴酸加入浓硫酸中，再加入正丙醇，加热回流0.5h。于70-75℃将生成的溴丙烷全部蒸出，然后用浓盐酸洗，再用碳酸钠中和至pH为7。用无水硫酸钠干燥，过滤，滤液蒸馏，收集69-74℃馏分，得溴丙烷。（2）由正丙醇与溴化钠反应而得。将正丙醇和水、溴化钠一起加热至回流，保持69-72℃滴加硫酸，加毕，继续回流2h。蒸馏，收集68-100℃馏出液，用碳酸钠溶液洗至中性，再蒸馏，收集68-76℃馏出液即溴丙烷。另外，在红磷存在下，正丙醇与溴反应也可制备溴丙烷。
