1、 2,6-甲乙基苯胺与氯乙酸和三氯化磷进行反应，生成2,6-甲乙基-氯代乙酰替苯胺；乙醇与聚甲醛在盐酸存在下反应，醚化后得氯甲基乙基醚；最后2-甲基-6-乙基氯代乙酰替苯胺与氯甲基乙基醚进行缩合反应，即制得乙草胺。产品50%乳油为淡棕黄色液体；43%乳油为红棕色液体。原料消耗定额：2-甲基-6-乙基苯胺600kg/t、氯乙酸480kg/t、乙醇250kg/t、聚甲醛150kg/t、烧碱1100kg/t。

2、 2,6-甲乙基七胺与氯乙酸和三氯化磷反应，生成2，6-甲乙基-2-氯代乙酰替苯胺。
乙醇与聚甲醛与盐酸存在下反应，生成氯甲基乙基醚。
2,6-甲乙基-2-氯代乙酰替苯胺与氯甲基乙基醚缩合，生成乙草胺。

3.由2,6-甲乙基苯胺与氯乙酸和三氯化磷反应，得到2,6-甲乙基氯代乙酰替苯胺。乙醇与聚甲醛在盐酸存在下反应，生成氯甲基乙基醚。然后由得到2,6-甲乙基氯代乙酰替苯胺与氯甲基乙基醚缩合生成乙草胺。
