2.4-D丁酯制备

1.首先由苯酚氯化生成2,4-二氯酚，经碱溶液中和后与氯乙酸钠进行缩合反应，生成2,4-D钠盐，酸化后再与丁醇进行酯化反应即得。原料消耗定额：苯酚480kg/t、氯乙酸510kg/t、丁醇320kg/t、液氯720kg/t、盐酸（30%）520kg/t、液碱（折100%）630kg/t。

2. 2,4-滴的合成先合成苯酚钠与氯乙酸钠，然后两者缩合，反应在110～120℃下进行，反应过程维持溶液微碱性，一氯醋酸与苯酚投料比1∶1.16。然后进行氯化反应，以氯气为氯化剂，反应温度92～98℃。

3. 2,4-滴丁酯的合成将湿2,4-滴在搅拌下加入至定量丁醇中，升温至120～140℃，保持4h，充分脱水，丁醇回流。待分离器水面不再上升时，停止回流，升温至160～170℃，减压蒸出丁醇。
