Abstract: Carbon black having organic groups, the organic group containing a thiocyanate group. Also described is a process for the production of the carbon black, wherein carbon black is reacted with organic compounds containing a C—C double or triple bond, which is not part of an aromatic system, whose C—C double or triple bond is activated by at least one substituent, and the organic compound contains at least one thiocyanate group. The carbon black according to the invention can be used in rubber compounds.

Abstract: Furnace carbon black which has a hydrogen (H) content of greater than 4000 ppm and a peak integral ratio of non-conjugated H atoms (1250-2000 cm−1) to aromatic and graphitic H atoms (1000-1250 cm−1 and 750-1000 cm−1) of less than 1.22. The furnace carbon black is produced by injecting the liquid carbon black raw material and the gaseous carbon black raw material at the same point in a furnace carbon black process. The furnace carbon black may be used in the preparation of electrocatalysts.
