This paper reports a simple apparatus for the synthesis of fullerenes and an efficient method for the separation of C60 and C70 in large amounts. The positive and negative ion mass spectra of C60 and C70 were measured using electron ionization and in-beam methods. Vibrational Raman spectra showed that the C60 molecule adsorbed on the substrate surface may be distorted and its symmetry may be reduced under the action of the substrate surface.

The reaction of C60 with epihydrin, epichloro (bromo) hydrin and dichloromethane in the mass spectrometric ion source was studied. The methylene cation CH+. 2 and carbene radical : CH2 are formed while epihydrin, epichloro (bromo)hydrin and dichloromethane are ionized by electrons. The addition reaction between C+. 60 and : CH2 occurs in the ion source. A series of ions of cyclopropyl derivatives C60(CH2)+. n (n=1, 2, …, 5) has been analyzed by mass spectrometry.

The electroreduction of C-60 was investigated by microelectrode voltammetry and in situ optically transparent thin layer electrode technique(OTTLE). From the measurements of steady state polarization curves and the absorbance dependence of C-60 on reduction potentials, it is found that the electroreduction of C, occurs in a successive three step one electron reduction. The diffusion coefficient and standard equilibrium potential were evaluated to be 5.3 x 10(-6) cm(2).s(-1) and -0.40 +/- 0.02V (vs. Ag/AgCl) respectively.

The chemical ionization mass spectra of cyclic glycols and monosaccharides using formaldehyde dimethyl acetal as reagent gas have been studied. In the gas phase, the stereospecific reaction of methylene acetal formation was observed. From the relative abundances of the characteristic ions the stereoisomers of these compounds may be definitely distinguished.
