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 90°C. The drop in count rate on hyd

✦ Synopsis
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.

The introduction of peroxide groups onto carbon black surface was achieved through the trapping of the peroxide radicals formed by the decomposition of polymeric peroxide, such as poly(tetraethy1ene glycol peroxyadipate) (ATPPO), and bis-peroxide, such as l,l'-bis(t-buty1dioxy)cyclohexane (Perhexa-C
