An Invariant of Carbon Arc Synthesis of Fullerenes

摘要

The yields of fullerenes C60and C70were determined in a wide range of controlled parameters. The total yield of fullerenes varied from 3 to 24. The molar relative contents C60/C70appeared to be constant for all samples of toluene extracts of the soot and equal to 5.06 #xB1; 0.1. The accuracy of this constancy (#xB1; 2) was determined by application of a special mathematical processing to the spectra of toluene extracts.
