1、 先用苯酚氯化制得2,4-二氯酚,后者在氢氧化钠存在下与氯乙酸缩合生成2,4-D钠盐,再酸化成2,4-D原药。另一种新工艺是将苯酚和氯乙酸在碱性条件下先缩合,然后氯化而得。

2、 由2,4-二氯苯酚与一氯乙酸在NaOH溶液中加热回流制得2,4-二氯苯氧乙酸钠,再用盐酸酸化而成。

3、 以苯酚为原料,先与氯乙酸缩合后经氯化,或先氯化后与氯乙酸缩合均可制得产品。(1)先缩合后氯化工艺。将苯酚置于反应釜,加热熔融,先后投入2.2倍(摩尔比)地氢氧化钠和1.2倍(摩尔比)地氯乙酸,并在100-110℃下反应30min。反应物冷却后,用盐酸中和,可析出苯氧乙酸,收率82%以上。
苯氧乙酸于65-90℃下,缓慢通入1.4倍-1.6倍(摩尔比)地氯气,氯化产物即2,4-二氟苯氧乙酸,收率89%。
(2)先氯化后缩合工艺。将熔融的苯酚置于氯化器中,在45-65℃下通氯约8-9h,当反应物料相对密度达1.406(40℃)时氯化反应结束。反应物趁热加入30%的氢氧化钠溶液,加热至沸后,滴加氯乙酸钠溶液,并回流4-5h。稍冷后用30%的盐酸中和至PH1-3。趁热加苯萃取,并分出有机层。冷却后析出白色结晶,经抽滤、烘干得成品。

4、 以苯酚为原料,先与氯乙酸缩合后经氯化,或先氯化后与氯乙酸缩合均可制得产品。
先缩合后氯化工艺
将苯酚置于反应釜,加热熔融,先后投入2.2倍(摩尔比)的氢氧化钠和l.2倍(摩尔比)的氯乙酸,并在100~110℃下反应30min。反应物冷却后,用盐酸中和,可析出苯氧乙酸,收率82%以上。
苯氧乙酸于65~90℃下,缓慢通入1.4~1.6倍(摩尔比)的氯气,氯化产物即为2,4-二氯苯氧乙酸,收率89%。
先氯化后缩合工艺
将熔融的苯酚置于氯化器中,在45~65℃下通氯约8~9h,当反应物料相对密度达1.406(40℃)时氯化反应结束。反应物趁热加入30%的氢氧化钠溶液,加热至沸后,滴加氯乙酸钠溶液,并回流4~5h。稍冷后用30%的盐酸中和至Ph值1~3。趁热加苯萃取,并分出有机层。冷却后析出白色结晶,经抽滤、干燥得成品。
