标题:一种2,4-二氯苯氧乙酸的制备方法
摘要:本发明提供了一种2,4‑二氯苯氧乙酸的制备方法,包括以下步骤,首先将醇和卤代乙酸反应后,得到卤代乙酸酯;将2,4‑二氯酚与碱反应后,得到2,4‑二氯酚盐;然后将上述步骤得到的卤代乙酸酯与2,4‑二氯酚盐进行反应,得到2,4‑二氯苯氧乙酸酯;再将上述步骤得到的2,4‑二氯苯氧乙酸酯进行水解反应,得到2,4‑二氯苯氧乙酸和醇;最后将上述步骤得到的醇回用于前述步骤,循环利用;所述醇为c原子数大于等于2的醇.本发明调整工艺路线,从基础上进行改进,反应过程清洁,产生的废水量少,水解副产物少,产品纯度高,转化率和收率较高;而且过程原料可循环利用,适合大规模工业化生产.
