采用石墨等离子体放电方法,建立了一套高效率制备C_(60)系列的工艺,成功地得到了纯的C_(60)。结果表明,反应气氛、电流密度与电极间距是影响制备过程的主要因素,氧化铝的活性、粒度及色谱柱的装填质量决定着C_(60)的分离效果。
Using graphite plasma discharge method, a set of C_ (60) series process with high efficiency was established, and pure C_ (60) was successfully obtained. The results showed that the reaction atmosphere, current density and electrode spacing were the main factors affecting the preparation process. The activity of alumina, particle size and column packing quality determined the separation effect of C_ (60).
