C_(60) 与苯同系物的电子束催化反应

The electron-beam catalysis reaction of C60 and benzene homologue

研究了电子束辐照对Ｃ６０的苯同系物溶液的影响。发现电子束在常温常压的氮气中作用于固体Ｃ６０，其红外图谱与未辐照的Ｃ６０图谱一致，说明Ｃ６０的化学结构没有发生变化；当电子束辐照Ｃ６０的苯、甲苯和二甲苯溶液后，被辐照样品的颜色从紫色变成褐色，并有大量褐色固体沉淀产生；这三种固体产物经红外光谱仪测定发现图谱中分别明显存在苯、甲苯、二甲苯以及Ｃ６０的各种基团的红外特征吸收峰；辐照的Ｃ６０苯和甲苯样品的清液经紫外光谱测定，已无Ｃ６０的紫外特征吸收峰；而辐照的Ｃ６０二甲苯样品的清液经紫外光测定仍有Ｃ６０的紫外特征吸收峰。

? The effect of electron-beam irradiation on the C60-benzene homologue solutions was investigated The structure of C60 is found unchanged when it is exposed to the electron beam at room temperature under normal atmospheric pressure However, a lot of brown deposition will be produced when the C60 dissolved in benzene homologue is irradiated with electron beam The infrared spectra of these brown deposits show typical IR absorption peaks of C60, benzene, toluene and xylene Supernatants of the irradiated C60-benzene homologue solution are measured by an UV spectrometer, showing that there is no C60 species in the supernatants of both C60-benzene and C60-toluene solution, while in the xylene solvent some quantity of C60 can still be observed
