Electron spectroscopy was applied to the study of a colour black (Carbolac 1) and of graphitic oxide, modified by esterification of the acidic surface groups. The deconvolution of the O,, spectra indicates that in the case of carbon black irreversible transformations of the surface structure occur,

Diazomethane has been used to methylate the "active" hydrogen associated with acidic oxides on carbon and graphite surfaces. Analysis of the methoxyl groups so formed showed that the active hydrogen was present as an OH group and that the total active hydrogen content of both carbon and graphite deg
