本文计算了不同温度下气相反应7/6 C60=C70的热力学函数, 讨论了C60与C70之间相互转化的热力学条件。结果表明, 温度高于2828K时气相中C60比C70稳定, 温度低于2828K时气相中C70比C60稳定, 解释了由石墨制备Fullerenes时, C60和C70含量不同的原因。

The thermodynamic functions for the gaseous reaction of 7/6 C60=C70 at different temperatures are calculated in this paper, and the thermodynamic condition of that C60 changes to C70 are discussed here. The results show that gaseous C70 is more stable than gaseous C60 as temperature below 2828K and gaseous C60 is more stable than gaseous C70 as temperature high 2828K. The reason of different content of C60 and C70 in the preparative process of Fullerenes has been explained.

Key words: THERMODYNAMIC FUNCTION, GRAPHITE, FULLERENES
