摘要
Conductive carbon black for use in depolarization masses in dry batteries is produced. To this end, an aqueous suspension of carbon black having an AS-number higher than 15 and having been obtained by subjecting hydrocarbons, which are liquid at room temperature, to thermal conversion at 1200 DEG -2000 DEG C, under 1-80 atmospheres, and in the presence of oxygen or oxygen-containing gas and, if desired, steam, and water-scrubbing the resulting carbon black-containing reaction gas, is intimately mixed at 5 DEG -120 DEG C, under 1-20 atmospheres, in liquid phase and for 1-20 minutes with 0.5-10 g, per gram of carbon black, of vaporizable aliphatic or cycloaliphatic hydrocarbons, the resulting carbon black is separated from the liquid phase, heated and thereby freed from hydrocarbons and water, and the temperature is finally increased for 2-30 minutes to 1100 DEG -2200 DEG C.
