β¦ Synopsis
and A. Turner (Lancashire Tar Distillers Limited, Cadishead, Manchester, U.K.). Nitrogen adsorption data at 77Β°K and carbon dioxide adsorption at 195*K on various coal and pitch solvent extract resin fractions is considered. The data is treated so that the monolayer capacity, the micropore volume, and equivalent measurements of adsorptive capacity can be obtained by the application of fundamentally diverse adsorption theories. The results demonstrate the applicability of the various theories.

Surface oxygen groups on carbon blacks were analyzed by several new techniques and some methods used previously were re-examined. Phenolic hydroxyl groups were converted to their acetate ester derivatives using radioactively labeled acetic anhydride in pyridine at 90Β°C. The drop in count rate on hyd
Three methods were employed to introduce sulfur groups (thiol and thio ester groups) onto the surface of a carbon black. Positive results were obtained and controled by functional group analysis and radiochemistry.
