摘要：
A Knudsen cell mass spectrometric study of pure C60 was carried out in the temperature range 600-800 K to obtain the vapor pressure and enthalpy of sublimation. The measured appearance potential for C60+ (8.1 +/- 0.5 V) is in good agreement with the recommended value (7.6 +/- 0.2 V) for the ionization potential of C60. The enthalpy of sublimation was found to be 181.4 +/- 2.3 kJ/mol at 700 K by the second law method. The vapor pressure of C60 is given as a function of temperature by the equation log (p/Pa) = -9777 +/- 138/T (K) + 11.582 +/- 0.126.
