生产方法及用途
生产方法
1.由烯丙醇溴化而得:向反应罐投入氢溴酸,在搅拌下加入硫酸、烯丙醇。升温回流2h,加热至8℃时有馏液蒸出,收集68-73℃馏分。水洗后,用无水硫酸钠脱水,过滤,得烯丙基溴。
2.制法: 于装有搅拌器、滴液漏斗、蒸馏装置的反应瓶中,加入250g(48%)的氢溴酸,慢慢加入75g浓硫酸,再加入烯丙醇58g(1.0mol)。搅拌下,滴加浓硫酸75g,加热反应瓶,滴加硫酸的同时,蒸出生成的烯丙基溴,约30min反应完。馏出液依次用5%的碳酸钠、水洗涤、无水氯化钙干燥,分馏,收集69~72℃的馏分,得烯丙基溴
(1)112g,收率93%。
用途
用于有机合成如合成染料、香料、医药工业上用于西可巴比妥的制造、农业上用作土壤熏蒸剂。
