正溴丁烷下游产品

正溴丁烷制备

1.由正丁醇在红磷存在下与溴作用而得；或由正丁醇在硫酸存在下与氢溴酸反应而得。正丁醇与氢溴酸混合，滴加入硫酸，加热回流反应1.5h，蒸馏得溴丁烷粗品，用水洗至pH为6-7，用无水氯化钙脱水即得。

2.制法：

于250mL反应瓶中加入水20mL，小心加入浓硫酸20mL。混合均匀后冷至室温。依次加入正丁醇（2）15g（0.2mol）、研细的溴化钠25g（0.24mol）。加入2粒沸石，装上回流冷凝器（顶部装一导气管至溴化氢吸收瓶）。加热回流反应1.5h，期间不断摇动反应瓶。冷后改为蒸馏装置，加热蒸馏，直至馏出液由浑浊变为澄清，得正溴丁烷粗品。将粗品水洗，分出有机层，以10mL浓硫酸洗涤，再依次用水、饱和碳酸氢钠、水洗涤，无水硫酸钠干燥，蒸馏，收集99～103℃的馏分，得正溴丁烷（1）16～18g，收率60%～65%。
