Abstract
Pitches were analyzed for the usual determinations including coking value, C-I, C-II, and atomic C/H ratio. Relative aromaticities of the pitches were also measured by refractive index and sulfonation index of pitch distillates, C/H ratio of the carbon disulfide soluble phase, and infrared index. The relative aromaticities agreed quite well among themselves but did not correlate with the usual determinations. It was shown that the density and reactivity of carbon anodes varied with the aromaticity of the binder pitch as measured by infrared index.
