生产方法
1.制法:
于装有搅拌器、回流冷凝器的反应瓶中,加入无水甲醇600mL,分批加入新切的金属钠50g(2.17mol),待钠完全反应后,搅拌下一次加入γ-环内酯
(2)344g(4mol)。尽快地蒸出甲醇475mL左右,再减压蒸出50~70mL,剩余物为双丁内酯(mp86~87℃)。搅拌下滴加浓盐酸,有二氧化碳放出,10min内共加入盐酸800mL。加热回流20min,水浴冷却(此时用乙醚提取,分馏,可以得到1,7-二氯-4-庚酮)。搅拌下尽可能快地滴加由氢氧化钠480g溶于600mL水配成的溶液,控制内温不超过50℃。加完后加热搅拌回流30min。蒸馏,收集650mL酮-水混合液,加入固体碳酸钾使之饱和,分出有机层,水层用乙醚提取3次。合并有机层,无水硫酸镁干燥,回收乙醚后减压精馏,收集72~74℃/4.39kpa的馏分,得产品
(1)114~121g,收率52%~55%。
用途
用作医药及农药中间体。
