研究了二苯并-18-冠-6在对二氧六环溶液中的紫外吸收光谱。并对该化合物进行了定量分析研究(λ_(max)~(对二氧六环)277nm,ε=5952),浓度在0.06～2.4mg/25ml范围内遵守比耳定律。可能存在的企属离子、卤素和水分对本测定无干扰。
The UV absorption spectra of dibenzo-18-crown-6 in dioxane solution were studied. (Λ max (~ dioxane) 277 nm, ε = 5952) were also studied. Beer’s law was obeyed at a concentration range of 0.06 ~ 2.4 mg / 25ml. The possible presence of ions, halogens and moisture has no interference with this assay.
