Web20 mei 2024 · Although fullerenes are composed of sp 2 carbons in a similar manner to graphite, fullerenes are soluble in various common organic solvents. Due to their hydrophobic nature, fullerenes are most soluble in CS 2 (C 60 = 7.9 mg/mL) and toluene (C 60 = 2.8 mg/mL). WebLet it be known that the actual process of making good quality C60 is not difficult – though sourcing a good quality fullerene C60 from the marketplace IS difficult, as we have found many suppliers to cut corners in the manufacturing process. The two main concerns are as …
