  • Process for removing extractable substances from carbon black
    Patent number: 4435378
    Abstract: A process for removing extractables from carbon blacks in a fluidized bed, wherein low extractable carbon blacks are treated under relatively mild temperature conditions (320.degree. C.) with an oxygen containing gas and high extractable carbon blacks are treated first at 100.degree.-320.degree. C. with steam and then at 200.degree.-500.degree. C. with an oxygen containing gas. A definition of classification in the "low extractable" and "high extractable" categories is given.

  • Carbon black useful for pigment for black lacquers
    Patent number: 4366138
    Abstract: An oxidized carbon black (gas black) is prepared within the MCC (medium color channel black) area showing primary particle sizes of an average diameter of 16 to 18 nm and a content of volatiles of at least 15% which, as secondary characteristics, has a specific surface area (BET) of 300 to 420 m.sup.2 /g, an oil absorption (stiff paste) conducted on carbon black powder of 430 to 560 g/100 g, an oil absorption (stiff paste) conducted on carbon black beads of 370 to 450 g/100 g, a pH value of 2 to 5, a nigrometer index of 68 to 72 and a maximum content of volatiles of 25%. The carbon black is used as a pigment in high jet black lacquers.
