【摘要】 介绍了用阳极弧蒸发石墨法合成Ｃ６０，Ｃ７０的技术，及Ｃ６０，Ｃ７０的萃取、提纯和液相色谱分离方法．着重研究了影响Ｃ６０，Ｃ７０产率的各种因素，如气体种类、弧电流、气压、石墨纯度等，得出了合成Ｃ６０，Ｃ７０的最佳条件：当氦气气压为２０ｋＰａ，弧电流为６５Ａ时，产率最高可达１５％；当氖气气压为１６ｋＰａ，弧电流为７０Ａ时，产率最高可达２１％．绘出了产率随氦气气压变化及弧电流变化的曲线，并给出了Ｃ６０，Ｃ７０的１３Ｃ核磁共振谱、红外吸收谱和质谱．更多还原

【Abstract】 The efficient production of C60,C70 by using D C arc vapor graphite rod is described in this paper. The extraction and purification of C60,C70are studied. Factors such as the kinds of gas, atmospheric pressure, arc current and purity of graphite rod, that affecting the yield rate of C60,C70 are studied in this paper. The best condition of production is described. When the pressure of helium is 20　kPa,and arc current is 65 A, the maximum yieldrate is 15%. When the pressure of neon is 16　kPa,and the arc current is 70 A, the maximum yieldrate is 21%. The yield ratehelium pressure curve and the yield ratearc current curve are mentioned. The 13　CNMRS,　FTIRS and MS of C60,C70 are presented.更多还原
