Electrolytic reduction of tetrachloro-2-picolinic acid in basic aqueous solution, at an activated silver cathode, yields the 3,4,6- and 3,5,6-trichloro-2-picolinic acids, which in turn may be further reduced to 3,6-dichloropicolinic acid, a highly active herbicide.
在碱性水溶液中,四氯-2-甲基吡啶甲酸在活化银阴极上进行电解还原,可生成 3,4,6- 和 3,5,6- 三氯-2-甲基吡啶甲酸,后者又可进一步还原成 3,6- 二氯-2-甲基吡啶甲酸,这是一种高活性除草剂。
