(RS)-1,4-Dibromopentane
1,4-Dibrompentan
性质描述: 具有臭味的液体。凝固点-34.42℃,沸点(19.998kPa)145-147℃(并略微分解),相对密度1.6222(20/4℃),折射率1.5085。
生产方法: 将2-甲基四氢呋喃用氢溴酸及硫酸开环溴化合成而得。先将氢溴酸加入反应锅内冷却,在搅拌下依次缓缓加入2-甲基四氢呋喃及硫酸,在温度不超过40℃时加完。升温到60℃,反应2h,再于80-85℃反应4h,冷却后,分取溴化物,用水洗至中性,得二溴戊烷油状物。收率92.5%。工业品含量在90%以上。原料消耗定额:2-甲基四氢呋喃(90%)410kg/t、氢溴酸(≥48%)2400kg/t。
用途: 主要在有机合成中用作烷基化剂,在医药工业中作为抗疟药磷酸伯氨喹的中间体。
