A new 1,3-dimethylurea–formaldehyde condensate, bis(1,3-dimethylureido)methane, was prepared and the molecular structure, as determined by X-ray analysis, and possible specific interaction to alkaline metal ions were compared with those of 1,3,5,7-tetramethyltetrahydro-1,3,5,7-tetrazocine-2,6(1H,3H)-dione. Although both structures are different from each other, their UV spectra in aqueous solution
制备了一种新的 1,3-二甲基脲-甲醛缩合物,双(1,3-二甲基脲基)甲烷,并通过 X 射线分析确定了分子结构,并将与碱金属离子可能的特定相互作用与 1 ,3,5,7-四甲基四氢-1,3,5,7-tetrazocine-2,6(1H,3H)-dione。尽管这两种结构彼此不同,但它们在水溶液中的紫外光谱表明碱金属离子 Li+ 和 Na+ 都被它们捕获。
