Abstract

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 degassed at temperatures up to 800°C was very close to the uptake of 0.05 N sodium hydroxide. Studies on the carbon black Spheron 6 showed that the acidic oxide decomposing at about 250°C was not methylated by diazomethane but the group decomposing around 600°C was rapidly methylated. In addition a group decomposing at 400-500°C was found to be slowly methylated by diazomethane. © 1978.
