With a MP of 113 C, melting it out is tempting - but how do I separate the carbon? By density? Carbon shouldn't be soluble in molten sulfur...
As for sublimation, it boils at 444 C - not exactly what I can do with a hotplate. A blowtorch, maybe, but that leaves me to worry about oxidation,
even if I just heat the metal crucible containing the sulfur from the outside. |
