CARBON BLACK
Carbon black with an OAN, measured on the beaded carbon black, of less than 120 ml/100 g. A process for the preparation of the carbon black is described, wherein a salt solution is converted into an aerosol and this is then introduced into the carbon black formation zone. The carbon black can be used in inks, paints, lacquers, printing inks and ink-jet inks, and for coloring plastics.
1 . A process for the preparation of gas black which comprises converting a salt solution into an aerosol with a gas and then introducing the aerosol into a carbon black formation zone, mixing said aerosol with a source of gas black raw material to form an admixture, subsequently heating said admixture to form said gas black.
2 . The process according to claim 1 , wherein the salt solution is an alkali metal or alkaline earth metal salt solution.
3 . The process according to claim 1 , wherein the salt solution is a potassium salt solution.
4 . The process according to claim 1 , wherein the salt solution is a potassium carbonate salt solution.
5 . A process for the preparation of gas black as claimed in claim 1 , which comprises converting a salt solution into an aerosol with a gas and then introducing the aerosol into a carbon black formation zone, mixing said aerosol with a source of gas black raw material to form an admixture, subsequently heating said admixture to form said gas black.
6 . The process according to claim 5 , wherein the salt solution is an alkali metal or alkaline earth metal salt solution.
7 . The process according to claim 5 , wherein the salt solution is a potassium salt solution.
8 . The process according to claim 6 , wherein the salt solution is a potassium carbonate salt solution.
9 . A gas black, wherein the OAN, measured on the beaded carbon black is less than 110 ml/100 g. prepared by a process comprising:
converting a salt solution into an aerosol with a gas and then introducing the aerosol into a carbon black formation zone, mixing said aerosol with a source of gas black raw material to form an admixture, subsequently heating said admixture to form said gas black or channel black.
