制备方法与用途

化学性质
本品为无色片状结晶,熔点36℃,沸点176~178℃/2.7kPa,难溶于水,易溶于醇、醚、苯等有机溶剂。

用途
2-(2,4,6-三氯苯氧基)乙基氯是杀菌剂咪鲜胺的中间体。

生产方法
其制备方法是将2,4,6-三氯酚、氢氧化钾、二氯乙烷及催化剂加入醚化釜中,加热至105~110℃,釜内压力为300~400kPa,反应9小时后降温出料,经后处理得成品。

也可以用氯乙醇为原料制备2-(2,4,6-三氯苯氧基)乙基氯,具体方法是在反应釜中加入三氯酚和适量的氢氧化钠,加热使三氯酚溶解,在75℃左右滴加氯乙醇,滴加完毕后回流6小时。反应结束后加入适量甲苯,分出甲苯层并水洗至中性,干燥脱溶得2-(2,4,6-三氯苯氧基)乙醇,熔点为74~75℃。

取上述2-(2,4,6-三氯苯氧基)乙醇,以甲苯溶解后加热至50℃,滴加一定量的氯化亚砜并升温至80℃反应。反应结束后降至室温,加入少量水以分解氯化亚砜,再洗至中性脱溶得到淡黄色液体,冷却结晶成固态,用甲醇重结晶得白色针状晶体成品。

  • 一种安全可靠的咪鲜胺的制备方法
    申请人:欧阳建峰
    公开号:CN110092757A
    公开(公告)日:2019-08-06
    本发明公开了一种安全可靠的咪鲜胺的制备方法,包括如下步骤:S1、醚化反应:2,4,6‑三氯苯酚、液碱、二氯乙烷、密封加热反应,得到S1醚化中间体;S2、胺化反应:加入丙胺,加热反应,蒸馏回收丙胺,萃取得S2仲胺中间体溶液;S3、酯化反应:加入缚酸剂A、卤代甲酸酯,室温反应1~3h,过滤得到S3酯化中间体溶液;S4、羰基化缩合反应:加入催化剂B、咪唑,回流反应,清洗、萃取、蒸馏得咪鲜胺成品。本发明采用卤代甲酸酯,替代类光气试剂作为羰基化缩合试剂,再辅以密封、无水、精馏回流的反应条件,实现了一种连续化生产工艺,其咪鲜胺的总收率较高,且无光气泄漏等安全隐患,值得推广。
