General description
氧化氘,一种氘代溶剂,是NMR(核磁共振)分析的标准固化溶剂。液态氧化氘的各种热力学性质(如分子间振动频率,氢键能,自由能,焓和熵)等都已得到了评估。D2O的电离常数(在5-50℃的范围内),pK值(在25℃)以及焓,熵,热容量变化(用于D2O的解离)都已被报道。
Application
在通过NMR的定量实验期间,氧化氘(重水,水-d2,D2O)已被用作溶剂用于溶解内部标准品和样品。它已用于溶解三(2,2′-联吡啶)二氯化钌(II)六水合物Ru(bpy)3.4
氧化氘还可用于:
- 通过与三氟乙酸酐反应制备三氟乙酸-d。
- 在钌催化剂存在下通过H/D交换反应作为伯醇和仲醇在β-碳位的氘代剂。
- 与六甲基二硅烷一起作为钯转移试剂,用于炔烃在钯络合物存在下形成(E)-1,2-二氘代烯烃。

Robust methods for differentiating long-lived nanobubbles from other nanoparticles are required. Evaluation of the density and compressibility of nanoparticles should enable nanobubbles to be differentiated from other nanoparticles, although the response of nanobubbles to pressure can be strongly influenced by
