光对水化学反应性的影响
Influence of light on chemical reactivity of water
摘要:
已经发现可见光、紫外线和X射线辐射增加水的化学反应性。经辐照的乙腈水溶液与亚磷酸三乙酯的反应速度比未经辐照的对照溶液快得多。这种现象是由于在光的影响下水分子团簇的分解,形成化学上更活跃的游离水分子。
英文摘要:
Visible light, ultraviolet and x-ray radiation have been found to increase chemical reactivity of water. The irradiated solution of water in acetonitrile reacts with triethyl phosphite considerably faster than the non-irradiated control solution. This phenomenon is accounted for by the decomposition of water clusters under the influence of light with the formation of chemically more active free water molecules.
