Abstract

Abstract Carbon disulphide is rapidly converted into sulphur by C60 deposited on neutral alumina, through formation of hydrogen sulphide which is then oxidised. C60 is more effective than graphite in this oxidation, which also occurs (though more slowly) in the absence of alumina. It is therefore essential to remove all traces of carbon disulphide traces when purifying C60 by column chromatography of soot extract deposited from carbon disulphide solutions.
