摘　　要：蒎烯醇(Trans-sobrerol,Sob)由α-蒎烯环氧化物水解产生,是α-蒎烯在大气中重要的氧化产物。溶液中的化学反应受溶剂的影响,同时液相反应也会受到反应物扩散系数的影响,我们采用核磁共振技术扩散排序谱法来测量Sob在水溶液中的扩散系数(diffusion coefficient,D),得到其自扩散系数为4.6×1010 m2/s,并且发现在一定的浓度范围内D不受浓度的影响。Trans-sobrerol（Sob） is hydrolysis product of α-pinene oxide and one of main oxidation products of α-pinene in atmosphere. Chemical aqueous reactions have influenced by solutions, as well as effected by diffusion coefficient of reactants. Diffusion ordered spectroscopy（DOSY） technology has been employed to detect diffusion coefficient of Sob, obtained the diffusion coefficient 4.6×10^10 m^2/s in D2 O solutions, and the D is not effected by concentration within a certain concentration range.
