Carbon black, method for the production thereof, and use thereof

摘要

The invention relates to a carbon black with a CTAB surface area of from 20 to 49 m2/g, with a COAN greater than 90 ml/(100 g), and with a sum of OAN and COAN greater than 235 ml/(100 g). The carbon black is produced in a furnace reactor, where from 20 to 55% by weight of the feedstock used for the carbon black are introduced radially through a nozzle within the first third of the reaction zone, and the remaining amount of the feedstock used for the carbon black is introduced through a nozzle upstream at least one further point into the reactor. The carbon black can be used in rubber mixtures.

1. A carbon black, comprising:
a cetyltrimethylammonium bromide (CTAB) surface area of from 20 to 49 m2/g; a compressed oil absorption number (COAN) greater than 90 ml/(100 g); and a sum oil absorption number (OAN) and COAN greater than 235 ml/(100 g), wherein a quartile ratio of the carbon black is greater than 1.60.
