环氧丙酸钾是一种专一性C_3植物光呼吸抑制剂.实验证明,对大豆、水稻和小麦等农作物施用它能收到一定增产效果.国内自十年前首次合成该化合物后,不少文章介绍了它的使用效果情况,但关于它的分子结构波谱研究以及它的标准谱,迄今未见文献报导.本文应用NMR手段,测定并归属了环氧丙酸钾样品的~1H及~(13)C—NMR谱信号,从而对其下列结构式I给予确认: Potassium epoxide is a specific photoresponsive C_3 plant photosynthetic experiments proved that soybeans, rice and wheat and other crops it can receive a certain yield-increasing effect of the domestic since the first synthesis of the compound ten years ago, not However, there is no report about its molecular structure and its standard spectrum so far.This article uses NMR method to determine and assign the ~ 1H and ~ (13) C-NMR spectrum signal to confirm the following structural formula I:
